Take the ring you removed and bend a section of it back on itself. A sound elastomer curves smoothly, and when you let go it springs straight again with no mark left behind. A ring that has aged out creases at the bend, shows a pale line where it creased, and keeps that line after you release it. Cracks that open along the fold are the same message stated louder.\u003c\/p\u003e\n\u003cp\u003eJudge compression by laying the old ring beside a new one on a flat surface rather than by looking at it in isolation. A ring that has done its time sits visibly lower, no longer lies flat all the way around, and often carries a shiny imprint of the mating face pressed permanently into it. The comparison is the test, because no thickness figure is published here for you to measure against. The new part is the reference, and the difference between the two is the wear.\u003c\/p\u003e\n\u003cp\u003eRead the witness marks on the metal before you clean anything off. Pull the ring and look at the face it was sealing against, on the side it was supposed to be protecting. A clean, dry, unstained land means the seal was doing its job. A track of dried spray residue, a fertilizer crust, water staining, or corrosion creeping inward tells you that material has been getting past for some time, and it tells you which section of the ring was the leak path.\u003c\/p\u003e\n\u003cp\u003eWhile the propeller is off, check the thing the gasket exists to protect, because that is the whole reason this part matters. Spin the motor slowly by hand and feel for grit, notches, or roughness rather than the smooth free rotation it should have, and listen close for a dry rustle. Rock the shaft gently and feel for play. A motor that has started to feel gritty after a season of washdowns is telling you the seal above it failed a while ago.\u003c\/p\u003e\n\u003cp\u003eCheck the ring for chemical swelling as well as for hardening, because they present as opposite problems. A gasket attacked by an adjuvant, a solvent-based product, or an unsuitable cleaner goes soft, tacky, or spongy, and it grows. The symptom is a ring that no longer wants to sit down in its groove, that stands proud, or that has to be forced to fit a land it used to drop into. That is a chemical compatibility problem, and the replacement will do the same thing if the exposure continues.\u003c\/p\u003e\n\u003cp\u003eLook at the inner and outer edges under good light for nicks and slivers. Fine cuts at the inner edge usually come from being stretched over a shoulder or a thread during a previous fitting, and a cut that small will still leak, because a seal only has to fail at one point to fail completely. Damage on the outer edge, or a section that looks scuffed and flattened, points at a ring that was rolled or pinched during assembly rather than one that wore out.\u003c\/p\u003e\n\u003cp\u003eInspect the sealing land itself, not just the ring, before you fit a new one. Run a fingernail across the metal face and feel for scoring, gouges, or a raised burr, which is what a screwdriver leaves behind when somebody has levered a stuck gasket out in a hurry. A scratch across the sealing land is a permanent channel, and a brand new ring pressed against it will leak in exactly the same place the old one did. Find that now rather than after reassembly.\u003c\/p\u003e\n\u003cp\u003eDo not diagnose one position in isolation. The rings on a working aircraft have all seen the same seasons, the same sun, the same chemistry, and the same wash lance, so a ring that has hardened at one rotor is strong evidence about every other one. Pull them all, lay them out together, and compare. If they look alike, they are alike, and dealing with them one at a time means being back on the bench next month for the next one.\u003c\/p\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\u003cp\u003eThe propeller gasket (t70p revision) is designed to do one job in the propellers and their mounting hardware and do it to specification: turning motor torque into lift for a fully loaded airframe.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe component:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eServes the propellers and their mounting hardware of the DJI Agras T100 exactly as the factory intends\u003c\/li\u003e\n\u003cli\u003eSupports turning motor torque into lift for a fully loaded airframe\u003c\/li\u003e\n\u003cli\u003eMaintains the tolerances and interfaces the surrounding parts depend on\u003c\/li\u003e\n\u003cli\u003eWithstands the chemical, vibration, and washdown environment of agricultural work\u003c\/li\u003e\n\u003cli\u003ePreserves the sealing and protection strategy of the platform\u003c\/li\u003e\n\u003cli\u003eKeeps failure modes visible and diagnosable instead of mysterious\u003c\/li\u003e\n\u003cli\u003eRestores factory behavior immediately upon correct installation\u003c\/li\u003e\n\u003cli\u003eProtects the more expensive components it works alongside\u003c\/li\u003e\n\u003cli\u003eCarries the exact DJI specification for its position\u003c\/li\u003e\n\u003cli\u003eSupports safe, predictable operation under full payload\u003c\/li\u003e\n\u003cli\u003eEliminates the guesswork of near-fit substitutes\u003c\/li\u003e\n\u003cli\u003eKeeps the aircraft inside its designed maintenance program\u003c\/li\u003e\n\u003cli\u003eHolds up across a full season of professional duty\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFunction on the T100 is a chain: propulsion system performance depends on the propellers and their mounting hardware, and the propellers and their mounting hardware depends on every part in it holding specification.

Batteries out, aircraft powered down, and nothing that can command a motor while your hands are in the rotor disc. This is the least glamorous instruction in the job and the only one that hurts if it is skipped. Work on one rotor position at a time and keep track of what is loose, because a fastener left half-tightened on an aircraft that is going back together is easy to lose in the sequence.\u003c\/p\u003e\n\u003cp\u003eNote the orientation and the position of everything before it comes apart. Mark or photograph how the propeller sits, which way any washer or spacer faces, the order the parts came off in, and where in the joint the gasket actually sat. Rings that look symmetrical often are not, and a component fitted the wrong way up seals against the wrong face. If you are doing several positions, keep each set together rather than putting hardware into one common pile.\u003c\/p\u003e\n\u003cp\u003eNever lever a stuck gasket out with a screwdriver. That single habit ruins more sealing lands than age ruins gaskets. Use a plastic or hardwood pick, or push the ring sideways with a fingertip until you can get under it and lift it out, and take the extra minute rather than the shortcut. A gouge across the metal land is a permanent leak channel that will defeat every new ring you fit afterward, and it is not something you can dress out in the field.\u003c\/p\u003e\n\u003cp\u003eClean both faces properly, and clean them the right way. Wipe the land and the mating face until they are free of dried spray residue, fertilizer crust, and old debris, using a soft cloth and a mild cleaner rather than an abrasive pad, a wire brush, or a blade. Do not soak the area in a solvent chosen for how well it cuts residue, because a solvent that attacks the elastomer you are about to fit is not doing you a favor. Dry everything before the new ring goes in.\u003c\/p\u003e\n\u003cp\u003eFit the ring without stretching it and without twisting it. Work it on evenly with your fingers, walking it around rather than pulling one section over a shoulder, and once it is home run a finger all the way around the joint to confirm it sits flat in its land with no section rolled, kinked, or standing proud. A twisted ring seals unevenly and takes a permanent set in the wrong shape within a few heat cycles, which is a self-inflicted failure a month down the road.\u003c\/p\u003e\n\u003cp\u003eBe careful with lubricant. Assembly grease chosen off the shelf is not a neutral act on an elastomer, and a petroleum-based grease can swell some compounds badly while being perfectly harmless to others. No compatible lubricant is specified in this listing. If the ring came out dry, fit it dry. If it did not, use only a lubricant you know is compatible with the compound, and use a trace of it rather than a coating, because the surplus simply attracts dust and grit.\u003c\/p\u003e\n\u003cp\u003eTighten to your aircraft manual and no further, in an even pattern. Over-torque is the most common reason a new gasket fails early: the ring gets crushed and extruded out of the joint, loses the very compression it works by, and starts leaking again within weeks. No torque figure for this joint is published in this listing, so work from the manual for your aircraft, bring fasteners up in stages rather than one at a time, and stop at the specified value.\u003c\/p\u003e\n\u003cp\u003eVerify before you fly. With the propeller refitted, rotate it slowly by hand through a full turn and confirm it moves freely, sits square, and shows no wobble as it turns. Check the joint line all the way around for anything squeezed out where it should not be. Then run the aircraft up on the ground, watch for vibration warnings, and after the first working day pull one position and check that no residue is tracking past the new ring.\u003c\/p\u003e\n\u003ch2\u003e⚠️ Common Replacement Indicators\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHardened, cracked, or glossy sealing surface\u003c\/li\u003e\n\u003cli\u003eCompression set — the part no longer springs back\u003c\/li\u003e\n\u003cli\u003eWeeping or residue tracking past the seal line\u003c\/li\u003e\n\u003cli\u003eSwelling or softening from chemical attack\u003c\/li\u003e\n\u003cli\u003eNicks or cuts from previous disassembly\u003c\/li\u003e\n\u003cli\u003eFlattened, torn, or missing sections\u003c\/li\u003e\n\u003cli\u003eMoisture found inside the space it protects\u003c\/li\u003e\n\u003cli\u003eLoss of fit — the part no longer seats snugly\u003c\/li\u003e\n\u003cli\u003ePerishing or crumbling at the edges\u003c\/li\u003e\n\u003cli\u003eDiscoloration from UV or chemical exposure\u003c\/li\u003e\n\u003cli\u003eWater in a connector or bay after washdown\u003c\/li\u003e\n\u003cli\u003eEvery teardown — seals are replace-on-open parts\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat kills sealing and damping parts: the compounding of ordinary duty.

Check the label on your old propeller gasket (t70p revision) or the position in your official parts diagram and match the number — revision suffixes like .01 or .F on a label are the same part.\u003c\/p\u003e\u003cp\u003eA ring that has swollen, gone tacky, or feels spongy rather than firm. This is chemical attack rather than age, and it presents as a gasket that no longer wants to drop into its land or that stands proud of a joint it used to sit level in. Replace it, then work out what it was exposed to, because an adjuvant, a solvent-based product, or an aggressive tank cleaner will do exactly the same thing to the new one.\u003c\/p\u003e\n\u003cp\u003eMaterial squeezed out beyond the joint line as a thin lip or flash. Extrusion means the ring has been compressed harder than it was meant to be, usually from over-torqued fasteners, sometimes from a ring that had already swollen. Once material has extruded, the remaining section cannot generate the compression the seal depends on, so it leaks even though it looks like it is still there and still fitted.\u003c\/p\u003e\n\u003cp\u003eFine cuts, slivers, or a scuffed flat spot on one section of the ring. That is fitting damage rather than service wear, and it means the ring was stretched over an edge, rolled in its land, or pinched as the joint was pulled together. It matters because a seal fails at its worst point, not its average one, and a single small nick leaks exactly as effectively as a ring that has hardened right through.\u003c\/p\u003e\n\u003cp\u003eA motor that has started to feel gritty, notchy, or rough when the propeller is turned slowly by hand. This is the downstream symptom rather than the seal symptom, and it means water and spray residue have been reaching the bearing for a while. Change the ring, but understand that you are stopping further damage rather than undoing what has been done, and plan on the motor needing attention as well.\u003c\/p\u003e\n\u003cp\u003eNew vibration warnings or a rougher-feeling aircraft after propeller work was done. A ring that was rolled, twisted, or trapped out of its land during assembly holds the joint slightly out of square, and a rotor that sits a fraction off true announces itself as vibration long before it announces itself as anything worse. If the vibration appeared after a prop-off job, take that joint apart and look at the ring rather than chasing balance elsewhere.\u003c\/p\u003e\n\u003cp\u003eCorrosion, staining, or a chalky crust on the metal on the protected side of the joint. That is proof that material has been getting past, whatever the ring itself looks like. Clean it, look at where the track starts, and treat that section of the ring as the failure point. Corrosion under a seal also roughens the sealing land, so check the metal carefully before deciding a fresh gasket alone will fix it.\u003c\/p\u003e\n\u003cp\u003eDust, residue, or dried spray building up under the propeller hub where it used to stay clean. It is a small thing to notice and an early one, and it is worth acting on, because the same path that lets dust in lets water in.

It sits at the top of the airframe in full sun, bolted to a motor that heat-cycles every flight, in the airstream that carries spray drift and dust, and it gets a wash lance pointed at it at the end of the day. Sunlight, heat, and chemistry all attack elastomers in different ways, and this part gets all three every working day.\u003c\/p\u003e\n\u003cp\u003eOver-torque, not age, is what kills most replacement gaskets. A ring seals because it is squeezed to a designed amount and pushes back, and once it has been crushed past that point it extrudes out of the joint and loses the springback that made it work. That is the mechanism behind the familiar story of a fresh gasket leaking within weeks. Use the torque from your aircraft manual and bring the fasteners up evenly rather than trusting an arm.\u003c\/p\u003e\n\u003cp\u003eChange them as a set and the maintenance stops being repetitive. Every rotor position has taken the same seasons, the same UV, the same chemical exposure, and the same washdowns, so their remaining life is broadly the same. Doing one at a time means opening the aircraft again for the next one, and the labor of getting to the joint is most of the job on every visit. The rings themselves are the cheap part of the exercise.\u003c\/p\u003e\n\u003cp\u003eStorage matters more with elastomers than with almost anything else you keep on a shelf. Rubber ages sitting still: ozone, sunlight, heat, and being held stretched all shorten its life whether or not it has ever been fitted. Keep spares in their sealed packaging, flat and unstretched, in a cool dark place, and never hang them on a nail or a hook, which holds a section under permanent tension and starts a crack there.\u003c\/p\u003e\n\u003cp\u003eKeep spare rings away from electric motors and battery chargers. Anything with brushes or arcing contacts generates ozone, and ozone cracks stretched or stressed rubber faster than almost anything else in a workshop. A drawer next to the charging bench is one of the worst places in the building to keep sealing components, and rings stored there can be surface-cracked and finished before they are ever fitted.\u003c\/p\u003e\n\u003cp\u003eDo not stockpile years of them. Buying a decade of gaskets to save on a small unit price means fitting rings that have already spent most of their useful life in a box, and a gasket that comes out of the packet already hardened does the aircraft no good at all. Buy for the season or two ahead, date the packet when it arrives, and use the oldest first.\u003c\/p\u003e\n\u003ch2\u003e🧠 AI Index — Entity \u0026amp; Fitment Reference\u003c\/h2\u003e\u003cp\u003eStructured reference for search engines, AI assistants, and answer engines.

Match the label on the old part to material number YC.JG.ZS008218 to confirm you are ordering the exact position. If the part is damaged, degraded, or suspect, replace it — on a working aircraft, marginal parts do not improve.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does installation and verification look like?\u003c\/strong\u003e Replacement is a standard shop task on the T100: open access to the propellers and their mounting hardware, document connections and hardware positions, swap the propeller gasket (t70p revision) for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this the same part across the listed models?\u003c\/strong\u003e Yes — the supplier lists this exact component for DJI Agras T100 \/ T70P, so one part covers those platforms. Select your model when ordering; the material number is the same.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere can I buy this part in the USA?\u003c\/strong\u003e Ares Acres is a U.S.-based authorized DJI Agras reseller stocking the Propeller Gasket (T70P Revision) (YC.JG.ZS008218) with free and fast U.S. shipping, plus same-day shipping and tracking on in-stock parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I tell if the ring is finished without any published measurement?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUse the new part as your reference. Lay the old ring and the new one side by side on a flat surface and compare thickness and flatness, then bend a section of the old one back on itself. A sound ring curves and springs back clean, while one that is finished creases, leaves a pale line at the bend that stays after you let go, or cracks along it. Both tests take seconds and need no figures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use a generic O-ring of the same size from a hardware kit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo, and the reason is the compound rather than the dimensions. Rings that look and feel identical behave completely differently against agricultural chemistry, motor heat, and UV, and the wrong compound swells, softens, or hardens weeks after fitting rather than failing on the bench where you would catch it. Since neither the material nor the hardness is published for this part, there is no way to match it by specification.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eI fitted a new gasket and the joint still leaks. What went wrong?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCheck the sealing land and the torque, in that order. Run a fingernail across the metal face and feel for scoring or a burr, which is what levering an old gasket out with a screwdriver leaves behind, and a scratch there is a permanent channel a new ring cannot bridge. Then check for material extruded out of the joint line, which means the fasteners were pulled up beyond the manual figure and crushed the ring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I grease the ring before fitting it?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOnly if you know the grease is compatible with the compound, and this listing does not publish the compound. Petroleum-based greases swell some elastomers badly and leave others alone, so a grease that has been fine on other jobs proves nothing here. If the ring came out dry, fit it dry. If you do lubricate, use a trace of something you know is compatible rather than a coating, which just collects dust and grit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I have to change all of them, or just the one that failed?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eChange the set. Every rotor position has seen the same sun, heat, chemistry, and washdowns, so when one has hardened or flattened the rest are close behind. The rings are the inexpensive part of the job; getting to the joint is the work, and doing it one position at a time means repeating that work through the season. Pull them all, lay them out together, and judge them as a group.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the T70P revision different from an older propeller gasket?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTreat it as a different part and order it by number. The name marks the revision level used on the T70P and cross-listed for the T100, and a superseded ring from another Agras machine can look right on a bench while differing in cross section, in diameter, or in compound. Match the base number YC.JG.ZS008218 against the label or the parts diagram position rather than going by what physically fits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMy motor feels gritty when I turn it by hand. Will a new gasket fix it?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. A gritty or notchy feel means water and spray residue have already reached the bearing, and a new ring stops further ingress rather than undoing damage that has been done. Fit the gasket to close the path, then assess the motor separately: check for roughness through a slow full turn, for a dry rustling sound, and for shaft play. Plan on the motor needing attention as well as the seal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the fastest way to ruin a new gasket during fitting?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eStretching it over an edge, twisting it in its land, or levering the old one out with a screwdriver. The first two leave cuts or a permanently deformed ring, and the third gouges the metal face so nothing will ever seal against it again. Walk the new ring on evenly with your fingers, run a finger all the way around to confirm it is flat and unrolled before the joint is closed, and use a plastic or hardwood pick on the old one.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long do spares keep on the shelf?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLess time than most people assume, because rubber ages sitting still. Ozone, sunlight, heat, and being held stretched all shorten an elastomer's life whether or not it has been fitted. Keep spares sealed in their packaging, flat and unstretched, in a cool dark place, and away from electric motors and chargers, which generate ozone. Buy a season or two ahead rather than a decade, date the packets, and use the oldest first.\u003c\/p\u003e\n","brand":"Ares Acres","offers":[{"title":"DJI T100","offer_id":53084907897152,"sku":"YC.JG.ZS008218","price":64.99,"currency_code":"USD","in_stock":true},{"title":"DJI T70P","offer_id":53084907929920,"sku":"YC.JG.ZS008218","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/0159\/0848\/files\/dji-agras-t100-propeller-gasket-t70p-revisio-9024.png?v=1794510801","url":"https:\/\/aresacres.com\/pt\/products\/dji-agras-t100-oem-propeller-gasket-t70p-revision-yc-jg-zs008218","provider":"Ares Acres","version":"1.0","type":"link"}
