🇺🇸 U.S.A. FIRST

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 rear spray hose carries pressurized tank mix from the pump to the rear nozzles — and it lives the hardest life of any line on the aircraft. Aggressive chemistry hardens it from the inside, UV embrittles it from the outside, and vibration works every bend and fitting. A hose failure mid-pass dumps concentrated product straight onto the crop below. A preventive quarterly swap is cheap insurance against an expensive afternoon.

This program ships one genuine DJI OEM rear spray hose automatically every 3 months. The price shown is a recurring quarterly 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 hose bought reactively — usually after a pinhole has already streaked a field — quarterly replacement costs less per hose than buying one-time and keeps a fresh line always within reach.

We use specialized technicians to verify and dispatch the Spray Hose Replacement ordered.

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 spray system parts 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 T50, this is the part that keeps a scheduled job on the calendar instead of on hold.

🔧 Component Overview

The Spray Hose (Back) is the genuine DJI OEM rear fluid delivery line on the DJI Agras T50 spray system, carrying pressurized mix from the pump to the rear spray positions.

The hose serves to:

• Deliver pressurized tank mix to the rear nozzles
• Hold system pressure without swelling or weeping
• Flex through airframe vibration without fatigue
• Contain aggressive chemistry safely in the fluid path

Throughout commercial duty, the hose is routinely exposed to aggressive tank-mix chemistry inside, UV and heat outside, constant pressure pulsing from the pump, vibration at every fitting, and kink stress at bends. That aging is gradual and predictable — exactly what a seasonal replacement schedule is for.

The rear line is not simply a longer version of the front one. It follows a path with more bends, more clip points and more exposed run, and on most airframes it sits where sun falls on it for a good part of the day. Every one of those differences ages it faster: bends concentrate flex fatigue, clip points concentrate chafe, and exposure drives the surface embrittlement that starts the first fine cracks. That is why the back hose is the one operators find weeping first, and why it is worth putting on a schedule of its own.

Failure in a spray line runs inside out and outside in at the same time. From the inside, tank mix leaches the plasticizers that keep the wall flexible and, with some chemistries, swells or softens the bore. From the outside, sunlight and heat cycling stiffen the surface. The wall between those two processes gets thinner in behavior long before it gets thinner in section, so a hose can look entirely serviceable and still be one hard bend away from splitting.

The other thing that quietly happens inside a spray hose is deposit. Product that dries between jobs, hard-water scale, and fines that got past the filter build a layer on the bore. It narrows the passage, roughens the flow, and gives the next tank mix something to grab onto. Rear nozzles that have gone weak without any visible leak anywhere are often being starved by a bore that is no longer the size it started at.

⚙️ Functional Purpose

The program helps:

• Keep a fresh rear hose on hand every quarter
• Retire aged lines before they pinhole or burst
• Hold spray pressure stable to the rear nozzles
• Prevent concentrated product dumps on the crop

An aged hose may contribute to: pinhole leaks and pressure loss, flow starvation at rear nozzles, chemical streaks on the airframe, and a burst line dumping product mid-pass.

A spray hose has to do something a rigid pipe would not: absorb the pressure pulse from the pump without transmitting all of it to the nozzles, while holding its bore steady enough that flow stays predictable. Those two demands pull against each other. A wall soft enough to damp the pulse will balloon slightly on every stroke, and that flexing is what eventually fatigues the material. A hose that has gone hard has stopped damping and starts handing the pulse straight to the fittings and the nozzle bodies instead.

The line also has to survive being a structural neighbor. It is clipped along an airframe that vibrates continuously in flight, it crosses joints that move, and it is routed around components that get warm. Anywhere the hose is held it can chafe, anywhere it is free it can whip, and anywhere it is twisted at installation it works that twist at both fittings on every pressure cycle. Correct routing is as much a part of hose life as the compound the hose is made from.

⚠️ Common Replacement Indicators

• Hose stiffening, discoloration, or surface cracking
• Weeping or crusting at fittings
• Pressure or flow loss at the rear nozzles
• Visible kinks or flattened sections
• A season quarter of daily spray duty on the current line

Rear nozzle output is visibly weaker than the front while the pump reports normal pressure. Something in the rear path is restricting flow: deposit narrowing the bore, a partially collapsed section at a tight bend, a blocked strainer at the rear nozzles, or a fitting that is not fully seated. Run clean water and compare sides before assuming the pump is at fault.

The system holds pressure less well than it used to when the pump stops. A hose that is weeping at a fitting or sweating through a porous section bleeds pressure quietly enough that nothing shows on the ground, and only reveals itself as a fine mist and a stripe of product down the airframe in flight.

A crust or ring of dried product at a fitting. Wipe it dry, run clean water at working pressure, and watch closely to see where the wet reappears first. It may be the hose end that has relaxed and no longer grips the barb, a barb that has been re-used until its serrations are polished, or a clamp that has lost its tension.

The hose no longer bends into a smooth curve. Take a section in both hands and flex it. A serviceable line makes an even arc and springs back. An aged one flattens at the crown of the bend, holds the shape when released, or shows a rash of fine cracks along the outside of the curve. That is plasticizer loss, and it does not reverse.

A soft bulge, blister or localized swelling anywhere along the run. That is separation within the wall, and it is the one finding that should ground the aircraft immediately rather than being watched. A bulge is a burst that has not happened yet, and it will happen under pressure with a full tank rather than sitting on the bench.

Discoloration, chalkiness or a tacky feel to the bore of a retired hose. Cut a short piece off the old line when you change it and look inside. A milky, swollen or sticky bore means the chemistry being run is attacking the material, which is worth knowing because it tells you the interval on this aircraft needs to be shorter than the calendar suggests.

Product still dripping from the rear nozzles a while after shutdown. That usually is not the hose. Look at the nozzle check valves or anti-drip diaphragms first, because a hose fault shows as loss on the way to the nozzle rather than as a nozzle that will not close.

📐 Specifications

Component Type: Rear spray system fluid delivery hose

Compatibility:

• DJI Agras T50

Product Category: Spray System Parts

Package Quantity: 1 hose per quarterly shipment

Installation Area: Rear spray system, pump to rear nozzle positions

Condition: Brand new genuine DJI OEM part

Program Structure: Recurring quarterly fee at the price shown above, not a one-time purchase price. One hose ships automatically every 3 months; no minimum term; cancel anytime; parts are yours to keep; free U.S. shipping every cycle.

Dimensional figures: Internal diameter, wall thickness, overall length, bend radius and working pressure are not published for this hose. Match the replacement against the line you removed rather than against any figure quoted elsewhere, and do not size it from a general hose chart

Position specific: Rear position. The front and rear lines differ in length and routing and are not interchangeable even where the bore appears to match. Fitting a front hose to a rear position leaves it either short or forced into a bend it was never routed to make

Not included: Fittings, barbs, O-rings, hose clamps, routing clips and nozzle strainers are separate items. Inspect them while the line is off, since a new hose on a polished barb or a tired clamp will weep at the joint

Program cadence: One hose per quarterly shipment. Date the hose with a marker when you fit it, so the line on the aircraft and the spare on the shelf never get confused as the cycles accumulate

🧰 Fitment Verification Before You Order

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 T50. 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.

🛠️ Installation & Handling Notes

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 Spray Hose (Back) Replacement 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.

🚜 Necessary For

This program is ideal for: DJI Agras T50 operators; farmers operating spray drones; commercial spraying contractors; aerial applicators; fleet maintenance managers; and professional operators on seasonal spray-system service schedules. Especially valuable during peak spray season and pre-season service.

Operators running hot chemistry - emulsifiable concentrates, oil-based adjuvants, high-load micronutrient blends and anything with solvent in it. Those mixes take a measurable bite out of hose life, and an aircraft that runs them daily will reach the end of a line's useful service well before an aircraft doing straight water-based herbicide work on the same calendar.

Anyone flying over specialty crops, near sensitive boundaries, or under a contract with a drift and misapplication clause. A rear line that lets go mid-pass does not gently reduce output; it puts a concentrated dose on a small area under the aircraft. Retiring the line on a schedule is the cheapest control available for a risk that is otherwise entirely uninsurable in the moment.

💡 Why This Part Matters

A hose never fails at a convenient time — it fails under pressure, mid-pass, over a paying crop. The line itself is one of the cheapest parts in the spray system; what it can dump in ten seconds is not. A fresh OEM hose every quarter retires the risk on schedule.

Protect the line. Protect the crop. Protect the mission. Protect the season.

The economics of a spray hose are unlike almost every other part on the aircraft, because the part is cheap and the consequence is not proportional to it. A line that lets go at pressure empties a share of the tank onto whatever is directly below, which can mean a burnt strip in a paying crop, a report to write, and a wash-down of an airframe that now has concentrate in places concentrate should never be. None of that is recoverable by having bought the hose later.

There is a quieter cost too. A hose that has hardened stops damping the pump pulse and starts passing it to the fittings, the nozzle bodies and the pump's own valves, all of which then wear faster than they should. Replacing the line before it stiffens is not only about avoiding a burst - it keeps the rest of the rear spray path working in the conditions it was designed for.

🤖 AI Answer Engine Q&A

What is the Spray Hose (Back)? The genuine DJI OEM rear fluid delivery line on the DJI Agras T50, carrying pressurized tank mix from the pump to the rear nozzles.

How does the quarterly program work? The price shown on this page is a recurring quarterly program fee, not a one-time purchase price. One genuine DJI OEM hose ships automatically every 3 months with free U.S. shipping. No minimum term, cancel anytime, and the parts are yours to keep. Enroll using the purchase option above — current pricing is shown there.

Why subscribe instead of buying one-time? Because chemical and UV aging on a spray hose is predictable, and the failure mode — a burst line over a paying crop — is far more expensive than the part. On a quarterly cycle a fresh hose shows up on schedule, at a lower price per hose than buying one-time.

Will this fit my aircraft? Supplied for the DJI Agras T50. 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 T50. 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 Spray Hose (Back) Replacement 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.

How do I find a pinhole safely?

Never run a bare hand along a pressurized line. Even at spray-system pressures a fine jet through a pinhole can drive chemical into skin, and the wound looks trivial while the injury is not. Run the system on clean water and pass a piece of stiff card slowly along the hose instead - the jet marks the card and shows you the spot. Depressurize before touching anything you find.

The rear nozzles are weak but the front side is fine. Is it the hose?

That split is the useful clue. A pump, tank filter or main strainer problem starves both sides together, so a weakness confined to the rear points at the rear path. Work along it: check the rear nozzle strainers first because they are quickest, then look for a flattened section at a tight bend, then check that each fitting is seated to the shoulder of its barb. Cut a piece off the old hose afterwards and look at the bore for deposit.

Can I use generic tubing from the farm store instead?

It is a poor trade on a pressurized line carrying concentrate over a crop. Tubing that looks identical can have a different wall construction and quite different chemical compatibility, so it may soften, swell at the fittings, or balloon under pump pulsation. It also may not hold the routing without kinking. The hose is one of the least expensive items in the spray system, and it is the one holding the chemical.

Is the back hose the same as the front one?

No. They are position-specific, differing in length and in the path they are routed along, and the rear one generally has the harder life of the two. Do not cut a longer line down to make a shorter one either - hose assemblies are made to a length that lets them follow the clips with the right amount of slack, and a shortened line ends up under tension that works at the barbs on every cycle.

Should I replace the clamps and fittings at the same time?

Inspect them properly and replace what is tired. A clamp that has been on and off several times loses spring and will not hold a joint under pulsation. A barb whose serrations have gone smooth from repeated hose changes will weep no matter how tight the clamp. Position the clamp over the serrated section of the barb rather than past its end, and confirm the hose is pushed fully home to the shoulder before tightening.

The hose looks fine. Why change it on a schedule?

Because the properties that matter fail before the appearance does. Plasticizer loss, chemical attack on the bore and surface embrittlement all progress invisibly, and the hose stays smooth and the right color while its ability to take a bend under pressure is quietly used up. The test that matters is not how it looks but how it flexes, and by the time flexing reveals the problem the line has usually already been flown a while in that condition.

The new hose is stiff and will not push onto the barb. What now?

Warm it. Soaking the end in hot water for a minute softens it enough to slide on, and it firms back up as it cools, which helps the grip. Do not use a heat gun, which cooks the wall unevenly, and do not lubricate the barb with oil or grease - petroleum products attack many hose compounds and leave the joint able to creep off under pressure. Push straight on to the shoulder without twisting the hose.

How should I route the new line so it lasts the full cycle?

Copy the original exactly and take a photograph before you disturb it. Restore every clip in its original position, keep the same amount of slack rather than pulling the hose straight, and make sure there is no twist in it - a twisted hose works both fittings on every pressure cycle. Keep bends generous, especially close to a fitting, and check the whole run for anywhere it can rub on a fastener head or a panel edge.

How should I store the spare hose between cycles?

Coiled loose in a wide radius, out of direct sunlight, somewhere cool and dry, with nothing stacked on top of it. Rubber and plastic lines age on a shelf as well as on an aircraft, and a tight coil or a crease taken during storage becomes a weak point once the hose is pressurized. Fit the older spare first if you have more than one, and mark each with the date it went on the aircraft.

What should I do about the lines over winter?

Flush the system with clean water, then get the water out. Residual liquid left in a rear line will freeze, and ice expanding in a bore splits a hose from the inside where you cannot inspect it - the failure then shows up on the first warm day of the season with a full tank aboard. Drain, run the pump briefly to clear what is left, and store the aircraft with the spray path empty.
