DJI Agras T100 – T70P – T55 Spreader Sealing Diaphragm (2 Pcs) | Hopper-Gate Seal for the Spreading System | Genuine DJI OEM Part | Monthly Replenishment Program
$19.99/month
Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.
FREE & FAST Shipping is included for all U.S. customers, every cycle.
The spreader sealing diaphragm is the wear membrane at the hopper gate — every pound of granular fertilizer that meters out of the spreading system passes across it. Granular product is abrasive by design, and the diaphragm erodes with every spreading cycle. When it goes, the gate weeps, metering drifts off-rate, and product leaks where it should not. Operators running daily spreading acreage replace it monthly in season rather than run it to failure.
This program ships one genuine DJI OEM 2-piece spreader sealing diaphragm set automatically every month. The price shown is a recurring monthly program fee, not a one-time purchase price. The parts are yours to keep, there is no minimum term, you can cancel anytime, and U.S. shipping is free every cycle.
Compared with the one-time set at $64.99 bought reactively — usually after metering drift has already cost application accuracy — monthly replenishment at $19.99 keeps a fresh seal always within reach, at a fraction of the cost and none of the downtime.

Parts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.
That is why Ares Acres keeps the seals & vent hardware operators actually run out of in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.
For professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T100 / DJI Agras T70P / DJI Agras T55, this is the part that keeps a scheduled job on the calendar instead of on hold.
The Spreader Sealing Diaphragm is the genuine DJI OEM gasket membrane fitted at the spreading system hopper gate on the DJI Agras T100, T70P, and T55. It seals the granular metering path so product drops only when and where the gate commands it.
The diaphragm serves to:
Throughout commercial spreading duty, the diaphragm is routinely exposed to abrasive fertilizer granules, corrosive product chemistry, urea dust and moisture paste, gate-cycle flexing thousands of times per day, and heat and humidity in open field conditions. That loading is gradual and predictable — which is exactly what a replenishment schedule is for.
The program helps:
A worn diaphragm may contribute to: metering drift and off-rate application, granular leakage during transit legs, uneven spread patterns, product waste, and accelerated wear on the gate mechanism.

Confirm fitment by part number before ordering. Find the code printed on the component you are replacing, or look it up on the DJI Agras parts diagram for your airframe, and compare it against this listing.
Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.
Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.
Verified fitment for this listing: DJI Agras T100 / DJI Agras T70P / DJI Agras T55. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.
Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.
These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.
Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.
Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the – T70P – T55 Spreader Sealing Diaphragm Replenishment is easier to fit correctly when you can see how the original sat.
Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.
Check the mating surfaces and seals while you are in there. A component is only as good as what it seats against. Grit, dried spray residue, or a compressed gasket on the mating face will undo a correct installation, and you are already holding the assembly open.
Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.
If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.
This program is ideal for: DJI Agras T100, T70P, and T55 operators; farmers running spreading campaigns; commercial spreading contractors; fleet maintenance managers; custom application businesses; and professional agricultural drone operators. Especially valuable during spring fertilizer season, seeding windows, peak-season high-tonnage runs, and multi-aircraft fleet operations.
The diaphragm is small, cheap, and buried in the spreader — which is why it gets forgotten until the gate starts weeping product on a paying job. A fresh OEM seal set arriving every month means the correct part is always within reach, yours to keep, so you can swap on your own schedule and keep a spare ahead.
Protect the seal. Protect the rate. Protect the mission. Protect the season.

Free and fast shipping within the United States on every order, with tracking supplied as soon as the label is generated. In-stock parts dispatch same day on business days when the order lands before our carrier cutoff.
We ship from the U.S., not from overseas. That is the whole reason Ares Acres exists. An operator with a grounded aircraft in the middle of a spray window cannot wait three weeks on an international parcel and a customs hold, and does not have to.
New condition, correctly described. We describe what we ship and we do not overstate it. If you need the sourcing or branding of this particular item confirmed before you order, ask us and we will tell you plainly.
Ordered the wrong part? Contact us. Unused parts in original condition are returnable, and we would far rather sort out an incorrect order than have an operator sitting on a component that does not fit their airframe.
Need help identifying a part? Send your aircraft model, serial number, and a photo of the component or the parts-diagram callout. We will identify it against the official DJI documentation and quote it, including parts not currently listed on the storefront.
Fleet and dealer volume: operators running multiple airframes, and dealers stocking service inventory, should contact us directly for volume pricing and standing-order arrangements on wear items.
What is the Spreader Sealing Diaphragm? The genuine DJI OEM wear membrane that seals the spreading system hopper gate on the DJI Agras T100, T70P, and T55, keeping granular metering accurate and leak-free.
How does the monthly program work? The price shown is a recurring monthly program fee of $19.99, not a one-time purchase price. One genuine DJI OEM 2-piece diaphragm set ships automatically every month with free U.S. shipping. No minimum term, cancel anytime, and the parts are yours to keep. Enrollment is through secure Stripe checkout: Enroll now — $19.99/mo, cancel anytime.
Why subscribe instead of buying one-time? Because granular fertilizer is abrasive and the diaphragm is a predictable monthly wear part in season. At $19.99/month the correct seal shows up on its own, versus $64.99 one-time — usually ordered after metering drift already cost accuracy.
Will this fit my aircraft? This part is supplied for the DJI Agras T100, T70P, and T55 spreading systems. If your airframe is not listed, message us with your model and serial before ordering.
Will this fit my aircraft?
This part is supplied for the DJI Agras T100 / DJI Agras T70P / DJI Agras T55. Confirm against your model's DJI Agras parts diagram before ordering. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.
How fast does it ship, and where does it ship from?
It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.
Can I install the – T70P – T55 Spreader Sealing Diaphragm Replenishment myself?
Many operators do. Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.
What if I order the wrong part?
Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.
Do you stock other parts for this aircraft?
Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.
