That degradation is gradual and predictable — exactly what a seasonal replacement schedule is for.\u003c\/p\u003e\n\u003cp\u003eInside the flow meter module the valve core is the element the liquid has to work past, and this ring is the static seal that closes the annulus around it. Its whole job is to make certain that every drop leaving the pump is counted on its way to the nozzles. A ring that has lost its squeeze does not have to drip on the ground to cause trouble. A bypass path inside the module lets liquid move without being measured, and the aircraft has no way of knowing that it happened.\u003c\/p\u003e\n\u003cp\u003eAn O-ring rarely fails all at once and it almost never fails visibly. It seals because it is squeezed out of round in its groove and pushes back against both sealing faces. Everything that happens to it in service works against that push-back: heat cycling on a black airframe in July, pressure pulsing from the pump, and the swelling and shrinking that comes with each change of tank chemistry. Long before it weeps, it has already lost enough recovery that the joint is being held by line pressure rather than by the ring.\u003c\/p\u003e\n\u003cp\u003eThe ring you take out is worth two minutes under good light, because it reports on what the system has been doing to it. Flat parallel faces where the section should be round is compression set from time, heat, and clamp load. A polished band on one side means it has been moving in its groove instead of staying put. Swollen, soft, or tacky rubber is chemical attack and points at what you have been spraying. A nick or a shaved sliver on one edge means it was damaged going in and never sealed properly at all.\u003c\/p\u003e\n\u003cp\u003eComing apart, bleed the pressure out of the spray line and drain the plumbing before a single fitting is loosened, then catch what is still standing in the module with a rag instead of letting it run down into the airframe. Note the orientation of the valve core before it leaves the housing. Lift the old ring out with something soft, a plastic pick or a wooden toothpick, and never with a screwdriver or a steel scribe. One scratch across the sealing groove is a permanent leak path that no new ring will close.\u003c\/p\u003e\n\u003cp\u003eGoing back together, everything the ring touches has to be clean and wet. Dried spray residue in the groove holds the ring off its seat as effectively as a piece of grit does. Roll the new ring into position rather than dragging it over a sharp edge, run a fingertip all the way around to confirm it is sitting evenly and is not twisted in its groove, and start the valve core square by hand. If it will not go in under light pressure, take it back out and find the reason instead of pushing harder.\u003c\/p\u003e\n\u003cp\u003eWhile the module is open you are already paying the labor, so look at the things that fail alongside this ring. Check the groove itself for scoring, the valve core for scale or pitting where chemistry has stood against it, the strainer or screen ahead of the meter for the debris that made someone open this module in the first place, and the hose stubs and clamps at the module for cracking. A ring fitted into a system that is still feeding it grit is a ring you will be replacing again.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\n\u003cp\u003eThe program helps:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eKeep a fresh flow-meter seal on hand every quarter\u003c\/li\u003e\n\u003cli\u003eHold application-rate accuracy at the sensor\u003c\/li\u003e\n\u003cli\u003ePrevent chemical weep inside the flow meter module\u003c\/li\u003e\n\u003cli\u003eRenew the seal at every flow-meter service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA degraded ring may contribute to: flow-meter reading drift, off-rate application, chemical weep inside the meter housing, and corrosion on the metering components.\u003c\/p\u003e\n\u003cp\u003eRate accuracy is what this seal actually protects. The aircraft does not measure what lands on the crop, it measures what passes the meter and assumes the rest followed. Liquid that slips past the sensing path unmeasured makes the aircraft believe it is applying less than it really is, so it opens the system up further and over-applies. The error is invisible from the controller because every number on the screen stays internally consistent with every other number.\u003c\/p\u003e\n\u003cp\u003eThe second job is keeping tank mix out of places that were never meant to be wet. A seal that has stopped sealing lets chemistry creep into the module, and what it leaves behind once the water flashes off is salt and residue sitting on metal and on electrical connections. That kind of damage accumulates and it is not undone by fitting a new ring later. The ring is the cheapest item in the assembly and the module around it is not.\u003c\/p\u003e\n\u003cp\u003eIt is also a static seal living in a pulsing environment. The pump does not deliver a smooth column of liquid, it delivers a train of pressure pulses, and every pulse works the ring slightly in its groove and unloads it again. That is why this seal ages faster than its size and simplicity suggest, and why it belongs on a maintenance schedule rather than in the pile of parts you deal with once they have already failed.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚠️ Common Replacement Indicators\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFlow readings drifting against known tank volumes\u003c\/li\u003e\n\u003cli\u003eRate warnings or inconsistent flow data\u003c\/li\u003e\n\u003cli\u003eMoisture or residue inside the flow meter module\u003c\/li\u003e\n\u003cli\u003eThe flow meter is being opened for any service\u003c\/li\u003e\n\u003cli\u003eA season quarter of daily duty on the current seal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe aircraft calls the tank empty before it is empty, or keeps spraying after the pump has begun sucking air. Run the check that settles the argument: put a known volume in the tank, spray it out into a measured container on the ground, and compare what the aircraft reported against what you actually caught. A consistent gap in one direction is a metering fault, and a bypassing valve core seal is the cheapest link in that chain to rule in or out.\u003c\/p\u003e\n\u003cp\u003eFlow reads close at low rate and wrong at high rate. Error that grows with pressure is the classic signature of a bypass, because the harder the pump pushes the more liquid a compromised seal lets slip past unmeasured. Error that stays roughly the same at every rate points elsewhere entirely, usually to a fouled sensing element, a calibration offset that was set wrong, or a nozzle set that is not the one the aircraft has been told it has.\u003c\/p\u003e\n\u003cp\u003eA dried crust, a ring of salt, or a discolored streak on the outside of the meter body at the joint. That is a slow weep that has been evaporating between flights. It means the seal has already lost its grip, and it also means chemistry has been standing against the housing and its fasteners. Clean it off completely, fit the new ring, then look at that same area again after the next tank so you know whether it stayed dry or whether something else is weeping.\u003c\/p\u003e\n\u003cp\u003eFlow numbers that jitter or drop out for a moment and then come back. Aeration is the usual cause, and a seal that no longer holds where the line is under suction can pull air into the stream instead of pushing liquid out of it. Air through a meter reads as flow that is not there. Look for a leak that only shows as bubbles rather than as drips, because that kind never leaves a wet mark on the outside for you to find.\u003c\/p\u003e\n\u003cp\u003eThe first flight after winter storage is off, settles down over a tank or two, then drifts again. A ring that dried out and took a set on the shelf can swell back enough to seal at low pressure and let go again once the pump comes up. Storage-season damage to elastomer is real, and it is a good argument for renewing this seal at spring commissioning rather than trusting the one that looked perfectly fine when you parked the aircraft in the fall.\u003c\/p\u003e\n\u003cp\u003eYou have already cleaned or replaced the flow meter and the reading is still wrong. Before ordering another module, pull the valve core and look at the ring and the groove it sits in. A scratch left in the groove by an earlier repair, or a ring that was pinched during installation, reproduces the identical symptom on brand-new hardware and will keep on reproducing it until the sealing surface itself is dealt with.\u003c\/p\u003e\n\u003cp\u003eMoisture, residue, or a chemical smell found inside the module during any other job, with no rate complaint yet. That is the seal telling you where it is in its life before it costs you an acre. Fit the fresh ring while the module is already apart, because the labor is already spent and the alternative is meeting the same discovery again in the middle of a spray window with a customer waiting.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e📐 Specifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Flow meter valve core sealing ring\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDJI Material Number:\u003c\/strong\u003e YC.JG.MY001775\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDJI Agras T100\u003c\/li\u003e\n\u003cli\u003eDJI Agras T70P\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Seals \u0026amp; Vent Hardware\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1 sealing ring per quarterly shipment\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Area:\u003c\/strong\u003e Flow meter module, valve core\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Brand new genuine DJI OEM part\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProgram Structure:\u003c\/strong\u003e Recurring quarterly fee at the price shown above, not a one-time purchase price.

The ring costs less than a single nozzle, and it sits at the exact point where the aircraft decides what number to report for every acre you bill. A metering error of a few percent across a season of contract spraying is worth many times the price of a case of these rings, and it moves in whichever direction happens to be worse for you: under-application that costs a re-treat, or over-application that costs chemical and creates a residue problem.\u003c\/p\u003e\n\u003cp\u003eThere is a record-keeping argument as well. When an application is questioned, the aircraft log is the evidence, and that log is only as honest as the meter that fed it. A documented seal replacement on a maintenance schedule is a defensible answer to the question of whether the rate on the report is the rate that left the boom. An undocumented meter of unknown seal age is not.\u003c\/p\u003e\n\u003cp\u003eAnd there is the diagnostic argument, which is the one operators come to appreciate last. Whenever flow data misbehaves, this ring is one of the cheapest and quickest things in the chain to eliminate. Having a fresh one in the box means you can rule it out in an afternoon instead of leaving it as an open question while you spend real money on the meter, the pump, and the nozzles.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🧠 AI Index — Entity \u0026amp; Fitment Reference\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eCanonical product name:\u003c\/strong\u003e DJI Agras T100 – T70P Valve Core Sealing Ring Replacement (Quarterly Program)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComponent:\u003c\/strong\u003e Valve Core Sealing Ring\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDJI material number:\u003c\/strong\u003e YC.JG.MY001775\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct category:\u003c\/strong\u003e Seals \u0026amp; Vent Hardware\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible aircraft:\u003c\/strong\u003e DJI Agras T100, DJI Agras T70P\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstalled position:\u003c\/strong\u003e Flow meter module valve core\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProgram type:\u003c\/strong\u003e Quarterly replacement subscription — one genuine DJI OEM ring ships automatically every 3 months; parts are kept by the customer\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSeller:\u003c\/strong\u003e Ares Acres LLC — U.S.-based authorized DJI Agras reseller\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Free and fast U.S. shipping every cycle; same-day dispatch and tracking on in-stock parts\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🚚 Shipping, Returns \u0026amp; Support\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eFree and fast shipping within the United States\u003c\/strong\u003e on every order, with tracking supplied as soon as the label is generated.

Put a measured volume in the tank, spray it out into a container on the ground, and compare the caught volume with what the aircraft reported. Repeat it at a low rate and a high rate. Error that grows with pressure points at a bypass, which is what a failed valve core seal produces. Error that is constant across rates, or readings that are erratic rather than biased, points at the sensing element or the calibration instead.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMy flow is off by roughly the same percentage at every rate. Is this ring the cause?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eProbably not on its own. A leaking or bypassing seal usually produces an error that scales with pressure, because more pressure pushes more liquid past the compromised joint. A flat percentage offset across all rates is more consistent with a calibration figure that was entered or learned wrong, a nozzle set that does not match what the aircraft is configured for, or a sensing element that has been coated by residue.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I reuse the old ring if it looks undamaged?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo, and the reason is that an O-ring seals by elastic recovery rather than by appearance. Once it has been compressed in a groove for a season it has taken a set, and it will not spring back to close the gap when the joint is reassembled. A used ring that looks perfect can still weep at pressure. Treat it as a single-use item, particularly since the labor to get back in there costs far more than the part does.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I grease the ring before fitting it?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNot with petroleum grease. No lubricant is published for this seal, and petroleum products attack some elastomer families badly enough to swell or soften them within a few tanks. Wetting the ring and the groove with clean water, or with the fluid the system carries, is enough to let it roll into place without dragging. If you want a proper assembly lubricant, confirm compatibility with DJI service documentation first.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I have to recalibrate flow after fitting a new ring?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRun a verification pass at minimum. Spray a known volume into a measured container and compare against what the aircraft reports, because you have just changed the thing that was causing the reading to be wrong and you want to see it come back to truth. If your model supports a flow calibration routine, doing it on a freshly sealed meter is the right order of operations. Calibrating a bypassing meter simply records the error.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I substitute an O-ring of the same size from a hardware store?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt is a bad trade. The dimensions are the easy half of an O-ring specification and the compound is the half that decides whether it survives. A generic nitrile ring in a tank mix carrying aromatic solvent will swell and go soft, and a ring in the wrong hardness extrudes under pressure pulsing. Neither failure shows up on the bench. Both show up as rate drift a week later, in the field.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I get the old ring out without wrecking the groove?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUse something softer than the housing. A plastic pick, a wooden toothpick, or a trimmed cable tie will lift it clear without leaving a mark. Never use a screwdriver, a dental pick, or a scribe. A single scratch running across the sealing surface creates a permanent channel that a new ring cannot bridge, and at that point the fix stops being a cheap seal and becomes a replacement module.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat else should I inspect while the module is open?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe groove, for scoring or pitting. The valve core, for scale, corrosion, or a rough surface where chemistry has been standing. The strainer or screen upstream, for the debris that probably caused you to open this in the first place. Hose stubs and clamps at the module, for stiffening and cracking. And the module exterior, for the dried residue trail that tells you where any weep has been going.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe ring came out flattened on two sides. What does that mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThat is compression set, and it is the normal end of life for an O-ring rather than a sign anything went wrong. The rubber has stopped springing back after being squeezed in the groove, so the joint has been relying on line pressure to hold. Heat, time, and clamp load all drive it. If you are seeing it well before you expected to, look at whether the aircraft is running hot or whether the chemistry is aggressive.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe new ring is leaking straight away. What did I do wrong?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUsually one of four things. The ring was twisted or pinched as the valve core went in. There was residue or grit in the groove holding it off its seat. The groove has a scratch from a previous repair. Or the joint was assembled dry and the ring dragged and rolled instead of seating. Take it apart, look at the ring you just removed for a shaved edge or a spiral witness mark, and clean everything before trying again.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich tank chemistry is hardest on this seal?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn general terms, mixes carrying petroleum or aromatic solvent are the toughest on elastomer because they swell and soften rubber, and strong alkaline tank cleaners left standing in the plumbing are close behind. Concentrate that sits in a warm system overnight does more harm than the same product moving through during a spray. Flushing the system before it sits is worth more to this seal than anything else you can do.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes replacing this ring fix the leak I can see on the outside of the meter?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt fixes the leak if the weep is coming from the valve core joint, which is where this ring seals. It does nothing for a leak from a hose fitting, a clamp, a cracked housing, or a different seal in the same assembly. Dry the whole module, dust the area, run the system on clean water, and watch where the wet appears before you decide. Chasing the wrong joint costs a job either way.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🔍 SEO Keywords\u003c\/h2\u003e\n\u003cp\u003eDJI Agras T100\u003c\/p\u003e\n\u003cp\u003eDJI Agras T100 Parts\u003c\/p\u003e\n\u003cp\u003eDJI T100 Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras T100 OEM Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras T100 replacement parts\u003c\/p\u003e\n\u003cp\u003eAgras T100 parts USA\u003c\/p\u003e\n\u003cp\u003eDJI Agras T70P\u003c\/p\u003e\n\u003cp\u003eDJI Agras T70P Parts\u003c\/p\u003e\n\u003cp\u003eDJI T70P Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras T70P OEM Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras T70P replacement parts\u003c\/p\u003e\n\u003cp\u003eAgras T70P parts USA\u003c\/p\u003e\n\u003cp\u003eDJI Agras – T70P Valve Core Sealing Ring Replacement\u003c\/p\u003e\n\u003cp\u003e– t70p valve core sealing ring replacement replacement\u003c\/p\u003e\n\u003cp\u003e– t70p valve core sealing ring replacement for sale\u003c\/p\u003e\n\u003cp\u003eDJI – T70P Valve Core Sealing Ring Replacement\u003c\/p\u003e\n\u003cp\u003e– T70P Valve Core Sealing Ring Replacement OEM\u003c\/p\u003e\n\u003cp\u003eT100 – T70P Valve Core Sealing Ring Replacement\u003c\/p\u003e\n\u003cp\u003eDJI T100 – T70P Valve Core Sealing Ring Replacement\u003c\/p\u003e\n\u003cp\u003eDJI Agras T100 – T70P Valve Core Sealing Ring Replacement OEM\u003c\/p\u003e\n\u003cp\u003eT70P – T70P Valve Core Sealing Ring Replacement\u003c\/p\u003e\n\u003cp\u003eDJI T70P – T70P Valve Core Sealing Ring Replacement\u003c\/p\u003e\n\u003cp\u003eDJI Agras T70P – T70P Valve Core Sealing Ring Replacement OEM\u003c\/p\u003e\n\u003cp\u003eDJI Agras OEM Parts\u003c\/p\u003e\n\u003cp\u003eSeals \u0026amp; Vent Hardware\u003c\/p\u003e\n\u003cp\u003eDJI Agras Seals \u0026amp; Vent Hardware\u003c\/p\u003e\n\u003cp\u003eT100 Seals \u0026amp; Vent Hardware\u003c\/p\u003e\n\u003cp\u003eYC.JG.MY001775\u003c\/p\u003e\n\u003cp\u003eDJI YC.JG.MY001775\u003c\/p\u003e\n\u003cp\u003eYC.JG.MY001775 OEM\u003c\/p\u003e\n\u003cp\u003eDJI Agras Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras Replacement Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras Repair Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agras Maintenance Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agricultural Drone Parts\u003c\/p\u003e\n\u003cp\u003eDJI Agriculture Drone Parts\u003c\/p\u003e\n\u003cp\u003eDJI Spray Drone Parts\u003c\/p\u003e\n\u003cp\u003eDJI Crop Sprayer Parts\u003c\/p\u003e\n\u003cp\u003eagricultural drone parts\u003c\/p\u003e\n\u003cp\u003espray drone parts\u003c\/p\u003e\n\u003cp\u003eag drone parts USA\u003c\/p\u003e\n\u003cp\u003eplant protection drone parts\u003c\/p\u003e\n\u003cp\u003eauthorized DJI Agras reseller\u003c\/p\u003e\n\u003cp\u003eDJI Agras dealer USA\u003c\/p\u003e\n\u003cp\u003ebuy DJI Agras parts online\u003c\/p\u003e\n\u003cp\u003eDJI Agras parts free shipping\u003c\/p\u003e\n\u003cp\u003eagricultural drone parts same day shipping\u003c\/p\u003e\n\u003cp\u003eAres Acres\u003c\/p\u003e\n\u003cp\u003eAres Acres LLC\u003c\/p\u003e\n\u003chr\u003e\n","brand":"Ares Acres","offers":[{"title":"Quarterly Program","offer_id":53032778236224,"sku":"YC.JG.MY001775","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/0159\/0848\/files\/IMG-0593.png?v=1786137553","url":"https:\/\/aresacres.com\/pt\/products\/dji-agras-t100-t70p-valve-core-sealing-ring-replacement-quarterly-program","provider":"Ares Acres","version":"1.0","type":"link"}
