The DJI AGRAS T100 water tank is the kind of part that looks simple until a repair team has to order it under time pressure. It is large, obvious, and easy to describe in a message. That is exactly why the order still needs discipline. A big visible part can create false confidence. The buyer still has to confirm the aircraft model, product page, material number, and the reason the tank is being replaced.

The product anchor for this guide is DJI Agras T100 Water Tank Assembly (1) Parts & Accessories - UNITED UAV Replacement Components. For broader T100 browsing, use the DJI AGRAS T100 parts collection. The collection helps repair teams compare nearby assemblies, while the product page identifies the commercial item for this order.

DJI's official AGRAS T100 specifications provide useful model context. They describe a large agricultural aircraft and list a 100 L HDPE spray tank configuration. That supports the operational importance of getting tank-related orders right, but it does not replace the UNITED UAV product page, and it does not prove official dealer status, warranty handling, or repair approval. Treat official model data as background. Treat the current product page as the ordering record.

Why A Tank Order Still Needs Evidence

Because a tank is large, people often assume there is only one thing to order. That can be risky. The repair note still needs to say whether the team is replacing the tank itself, confirming an assembly boundary, checking fittings, or documenting a crack, thread problem, impact mark, or contamination concern. A vague note such as "T100 tank needed" may be enough to start a conversation, but it is not enough to close the order.

A better note includes:

• DJI AGRAS T100 as the aircraft model.
• The exact product URL.
• The selected material number.
• A wide photo showing the aircraft area.
• A close photo showing the tank neck, mounting tab, surface damage, or fitting area.
• A plain reason for replacement.

That record helps the buyer, technician, and manager stay aligned. It also keeps the product page from being used as a shortcut for a diagnosis that still belongs to the repair team.

Current T100 Water Tank Material Number

At the time of this preparation, the linked UNITED UAV product page listed one available variant:

• YC.JG.CS000050 - Spray Tank (100L)

The low variant count does not mean the workflow can be casual. It means the decision is narrower, and the evidence should be cleaner. If the product page currently points to a single material number, the team should make sure the aircraft condition actually points to that assembly and not to a hose, clamp, cap, fitting, mounting item, or adjacent spray-system component.

This is where field photos matter. A cracked tank wall, damaged neck, damaged mounting tab, and missing fitting can all be described as a "tank issue" in casual speech. They may not all lead to the same order. If the linked product page is the right item, record YC.JG.CS000050 clearly. If the issue may belong to a neighboring component, stop and compare the collection before purchasing.

A Practical Lesson From The Bench

A seasoned repair coordinator would usually say: "Big parts still need small evidence." That line fits this T100 tank order well.

Large plastic parts are easy to spot, but the final ordering mistake often hides in a small area: a fitting, thread, bracket, clamp, or place where the tank meets another assembly. When the aircraft is being prepared for work, people naturally want a fast answer. The repair lead's job is to slow the decision just enough to prevent a second shipment.

One practical habit is to take three photos before the part is moved: one wide aircraft photo, one medium photo showing how the tank sits, and one close photo of the actual damage or connection point. If the tank is already off the aircraft, add a bench photo with the removed fittings nearby. Do not rely on memory. Once a tank is cleaned, moved, or separated from hoses and clamps, the original context gets fuzzy.

How To Use The Product Page

Open the T100 water tank assembly product page when the repair team is ready to move from diagnosis to purchasing. Confirm that the title, image, and material number match the part being requested. If the product page shows YC.JG.CS000050 - Spray Tank (100L), write that exact material number in the order note.

Then check whether the request includes anything outside that material number. If the technician also needs a hose, clamp, cap, or fitting, do not assume it is included unless the product record says so. That is a common source of delay: the main part arrives, but the small connecting item was never ordered.

Tank-Specific Photo Checks

For a water tank assembly, the most useful photos are not always the prettiest photos. A straight product-style photo can prove the tank is present, but the repair decision usually needs context. Take a wide photo showing where the tank sits on the aircraft. Take a close photo of the filler neck or fitting area. Take another close photo of the mounting tab, crack, abrasion, stain, or impact point that caused the replacement discussion.

If the problem is contamination, keep the note factual. Do not write chemical conclusions that the team has not tested. Say what was observed: residue, staining, odor, visible debris, or customer-reported contamination. If the issue is impact damage, show the part from two angles so the buyer can see whether the damage is only cosmetic or whether it affects a mounting or sealing area. The product page helps identify YC.JG.CS000050, but the photos explain why that material number is being ordered.

This is also where a senior technician's habit matters: do not wash away evidence before the buyer has enough photos. Cleaning the tank may be necessary for safe handling, but if the evidence disappears first, the order note becomes weaker.

What The Official T100 Context Supports

The official T100 specifications are useful because they establish that this is a high-capacity agricultural platform with a 100 L tank context. For content and ordering, that supports a simple point: tank-related downtime can affect a serious operating workflow. But the article should not turn model context into unsupported claims.

This guide does not state that UNITED UAV is an official DJI dealer. It does not claim the product is genuine DJI unless the product page itself supports that claim. It does not provide torque values, installation procedure, or flight-readiness approval. It stays with product identification, buyer evidence, and ordering discipline.

When To Pause Before Ordering

Pause if the product page image and the aircraft photo do not tell the same story. Pause if the complaint mentions leaking but the visible damage is on a hose or clamp. Pause if the aircraft has already been disassembled and nobody recorded where the fittings came from. Pause if the team is trying to add unrelated spray-system parts without checking their own product records.

Those pauses do not mean the order is wrong. They mean the evidence is not finished. A good repair desk would rather spend ten minutes clarifying the boundary than ship one large tank and discover that the original issue was a fitting, seal, or hose that was never included.

Internal Links For This Batch

If your team is building a larger parts plan, compare this tank workflow with the DJI AGRAS T50 parts planning guide and the DJI AGRAS T40 parts planning guide. The T50 and T40 articles deal with front shell planning, where several small shell-related variants can be involved. This T100 guide shows the same evidence habit for a large tank assembly.

FAQ

Is there only one current material number for this product page?

At the time of preparation, the page showed one available variant: YC.JG.CS000050 - Spray Tank (100L). Recheck the live page before ordering because product records can change.

Should a team order the tank whenever there is a spray-system issue?

No. Confirm whether the failure belongs to the tank body itself or to a connected item such as a hose, fitting, clamp, cap, or neighboring assembly.

Why link to official DJI T100 specifications?

Official model specifications provide background context for the aircraft and tank capacity. They do not replace the UNITED UAV product page for ordering.

What is the safest field habit?

Take wide, medium, and close photos before moving the part. The biggest item on the bench is not always the only item needed for the repair.
