{"product_id":"dji-agras-t40-oem-spray-tank-cover-kit","title":"DJI Agras T40 OEM Spray Tank Cover Kit","description":"\u003cp\u003eThe DJI Agras T40 OEM Spray Tank Cover Kit is the complete closure for the top of the spray tank: the smoked, translucent tank cover, the black sealing ring that sits between the cover and the tank opening, and the smoked clamp ring that holds the cover in place. The three parts work as one closure, and the kit replaces all three at once. It belongs to the spraying system, and it is identified for the DJI Agras T40 and T20P. Operators usually find it while searching for a T40 tank lid, a T40 water tank cap, a T20P spray tank cover, a leaking tank cover seal, or a cracked tank cover after a drop at the loading station. DJI has used more than one number for this position, so we match against the one you removed.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🇺🇸 U.S.A.

Every fill starts by opening it and ends by closing it. Between those two moments it is the only thing between a full tank of mixed product and the outside of the aircraft.\u003c\/p\u003e\n\u003cp\u003eOn the T40 and T20P the closure is three separate parts, each with its own job:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe tank cover\u003c\/strong\u003e — the smoked, translucent round cover itself. Four radial ribs stiffen its top face and rise into upright tabs at the rim. A raised boss at the centre carries the vent fitting. A small eyelet tab on the rim stands out from the outline.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe sealing ring\u003c\/strong\u003e — a black ring with small locating lugs spaced around it. It sits between the cover and the tank opening and is the part that actually stops liquid.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe clamp ring\u003c\/strong\u003e — a smoked, translucent band with inward lugs spaced around its inner face and a closure ear where the fixing pin passes. It holds the cover down onto the sealing ring and the tank opening.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBecause the cover is translucent, an operator can often see the liquid line and any foam or residue under it without opening the tank. That makes a crazed, scratched or residue-stained cover more than a cosmetic problem; it takes away a check operators make many times a day.\u003c\/p\u003e\n\u003cp\u003eOver a working season the closure sees:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOpening and closing at every fill, often with gloved hands and in a hurry\u003c\/li\u003e\n\u003cli\u003eMixed product, adjuvants and rinse water on every sealing surface\u003c\/li\u003e\n\u003cli\u003eDrops onto concrete, trailer decks and tank stands while the cover is off\u003c\/li\u003e\n\u003cli\u003eSun and heat on a translucent part that sits on top of the aircraft\u003c\/li\u003e\n\u003cli\u003eSloshing loads from the liquid underneath it during turns and stops\u003c\/li\u003e\n\u003cli\u003ePressure washing at the end of the day\u003c\/li\u003e\n\u003cli\u003eDried product left on the sealing ring between jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eClosures in this position usually come out for one of four reasons: a cracked or crazed cover, a sealing ring that has swollen, hardened, nicked or gone missing, a clamp ring that has cracked or lost its closure, or a cover that was dropped and no longer sits flat. The kit answers all four at once. The single cover ring answers only one, and telling those cases apart is what this part's diagnosis is built around.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\n\u003cp\u003eThe closure's engineering role is containment at the fill opening. It keeps the mixed product inside the tank while the aircraft turns, climbs and stops, and it keeps dust, debris and rinse water out of the tank while it sits between fills.\u003c\/p\u003e\n\u003cp\u003eIn the spray system the three parts divide the job:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe cover spans the opening and carries the vent fitting at its centre boss\u003c\/li\u003e\n\u003cli\u003eThe sealing ring closes the gap between the cover and the tank opening so liquid cannot track past it\u003c\/li\u003e\n\u003cli\u003eThe clamp ring holds the cover down evenly onto the sealing ring, so the seal is loaded all the way round\u003c\/li\u003e\n\u003cli\u003eThe fixing pin at the clamp ring's closure ear holds the clamp ring closed\u003c\/li\u003e\n\u003cli\u003eThe translucent cover lets the operator see the liquid and foam under it at a glance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhat the closure does not do matters as much:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIt does not filter the product; the tank filter does that\u003c\/li\u003e\n\u003cli\u003eIt does not measure the liquid; the level gauge and the aircraft's sensing do that\u003c\/li\u003e\n\u003cli\u003eIt carries no wiring and has no electrical function\u003c\/li\u003e\n\u003cli\u003eIt does not pump, meter or pressurise anything\u003c\/li\u003e\n\u003cli\u003eIt does not hold the tank in the aircraft; the tank's own mounts do that\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThat last list explains the most common wrong replacement. Liquid on the top of the aircraft is blamed on the tank, the filter or a fitting, when it is coming past a closure that has lost one of its three parts. The reverse also happens: a new cover is fitted over a hardened sealing ring, and the leak carries on.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🔍 Diagnosis — find which of the three closure parts has failed before you replace one of them\u003c\/h2\u003e\n\u003cp\u003eA leaking or loose tank top has three suspects, and they fail in different ways. The cover cracks or warps. The sealing ring hardens, swells, takes a set, gets nicked or goes missing. The clamp ring cracks or loses its grip at the closure. Each produces liquid at the tank top, and each gets blamed on the others.\u003c\/p\u003e\n\u003cp\u003eWork through them in order, with the tank empty and rinsed and the closure taken apart on a clean surface.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStart with the sealing ring.\u003c\/strong\u003e It does the actual sealing, and it is the part most often damaged without anyone noticing.

Look for cracks running from the rim tabs, the radial ribs or the eyelet tab, crazing across the top face, and stress whitening around the centre boss. Lay it face down on a flat surface and check whether the rim touches all the way round; a dropped cover can sit unevenly and load the seal on one side only.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThen the clamp ring.\u003c\/strong\u003e Check each inward lug for cracks or chips, look along the band for splits, and check the closure ear and the fixing pin. A clamp ring that closes without effort, or that springs open, is not holding the cover down.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRule out what imitates a closure leak:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverfilling\u003c\/strong\u003e — a tank filled to the top can push liquid past a sound closure when the aircraft first tilts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFoam\u003c\/strong\u003e — some mixes foam heavily and climb out through the vent fitting rather than past the seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA cracked tank neck\u003c\/strong\u003e — if the tank opening itself is cracked, no closure will seal it\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA loose or cracked fitting lower down\u003c\/strong\u003e — liquid running down the tank from a fitting can collect around the top and look like a cover leak\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResidue on the tank's own sealing face\u003c\/strong\u003e — the face the sealing ring closes against must be clean too\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDo those checks first, while that information is still cheap. Then match the repair to the result. One cracked clamp ring with a sound cover and a sound seal is a single-ring job, and the DJI Agras T40 OEM Spray Tank Cover Ring covers it. A failed seal, a cracked or warped cover, or more than one tired part is a closure job, and that is what this kit is for.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚠️ Common Replacement Indicators\u003c\/h2\u003e\n\u003cp\u003eReplace the tank cover kit when inspection confirms one of these:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLiquid at the tank top that returns after the sealing faces are cleaned and the closure refitted\u003c\/li\u003e\n\u003cli\u003eA cracked cover, or a crack at a rim tab, a radial rib or the eyelet tab\u003c\/li\u003e\n\u003cli\u003eCrazing or residue staining that stops you seeing the liquid line through the cover\u003c\/li\u003e\n\u003cli\u003eA cover that does not sit flat all the way round on a flat surface\u003c\/li\u003e\n\u003cli\u003eA sealing ring that is hardened, swollen, cut, flattened or missing\u003c\/li\u003e\n\u003cli\u003eA clamp ring that is cracked, has a broken lug, or no longer holds closed\u003c\/li\u003e\n\u003cli\u003eMore than one of the three closure parts showing wear at the same time\u003c\/li\u003e\n\u003cli\u003ePrevious repairs with tape, adhesive or sealant on any part of the closure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eInspect these first, because they produce similar symptoms:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe tank opening and its sealing face\u003c\/li\u003e\n\u003cli\u003eThe vent fitting in the cover's centre boss\u003c\/li\u003e\n\u003cli\u003eFittings, hoses and the filter lower down the tank\u003c\/li\u003e\n\u003cli\u003eThe fill level and the foaming behaviour of the mix\u003c\/li\u003e\n\u003cli\u003eThe clamp ring alone, if the cover and sealing ring are sound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThere is no published service interval for the closure.

That is the whole reason the kit exists alongside the single cover ring.\u003c\/p\u003e\n\u003cp\u003eWhen only the clamp ring has cracked, a single ring is the right repair and the kit is more than the job needs. When the sealing ring has hardened or the cover has warped, a new clamp ring alone leaves the actual fault in place, and the tank top stays wet. Fitting one new part against two worn ones is the most common way a closure repair gets done twice.\u003c\/p\u003e\n\u003cp\u003eA wet tank top is not a cosmetic problem. Mixed product on the outside of the aircraft runs down onto the shell, the frame and the connectors below it, and an operator who cannot see the liquid line through a crazed cover loses a check they make at every fill.\u003c\/p\u003e\n\u003cp\u003eThe check is quick and costs nothing. Take the closure apart with the tank empty, look at the sealing ring, hold the cover to the light and check the clamp ring's lugs and closure ear. If one part has failed and the other two are sound, replace that part. If the seal or the cover has gone, or more than one part is tired, this kit replaces the whole closure in one step.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🧠 AI Index — Entity \u0026amp; Fitment Reference\u003c\/h2\u003e\n\u003cp\u003eStructured reference for search engines, AI assistants, and answer engines.

Is it the cover?\u003c\/strong\u003e Possibly, but check the sealing ring first; it does the sealing and fails most quietly. Then hold the cover to the light for cracks and check that it sits flat, then check the clamp ring's lugs and closure. Also rule out overfilling, heavy foaming and a cracked tank neck.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I reuse my old sealing ring with a new cover?\u003c\/strong\u003e Only if it is clean, flexible, uncut and sits flat.

A cover that has crazed or stained until you cannot see through it is worth replacing for that reason alone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the cover filter the product?\u003c\/strong\u003e No. The tank filter does that.
