🇺🇸 U.S.A. FIRST

Ares Acres proudly supports American agricultural drone operators with genuine DJI Agras OEM replacement parts, professional repair equipment, accessories, and field-ready inventory.

FREE & FAST Shipping is included for all U.S. customers.

Every tank cap on an Agras closes on one small ring of rubber — and that ring is all that stands between a sealed tank and a chemical trail down the airframe. It compresses on every fill, soaks in product all day, and bakes in the sun between missions.

Sealing rings are the truest consumable on the aircraft. They flatten, they harden, they crack — quietly — and the first warning most operators get is product weeping from a cap that was tightened perfectly.

That is why Ares Acres keeps spray tank sealing hardware in stock and shipped fast to the U.S.A., helping operators keep tanks sealed, minimize downtime, and keep their aircraft spraying when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators, fresh seals are pennies of rubber protecting dollars of chemical.

🔧 Component Overview

The DJI Agras T40-T50 Spray Tank Cap Sealing Ring (2 Rings) is a two-piece seal kit for the spray tank caps of the DJI Agras T50, T40, T25, and T20P agricultural drones.

Each ring seats into the tank cap and compresses against the tank mouth to form the leak-proof seal the spray system depends on at every fill. Made from durable, wear-resistant material built for chemical contact, the rings restore factory sealing in seconds — and because the kit ships as a pair, one goes in the cap and one goes in the field kit, the way working crews actually run.

Commercial agricultural drones operate in demanding environments every day, including:

• Crop spraying
• Liquid fertilizer application
• Herbicide treatments
• Fungicide applications
• Insecticide spraying
• Orchard operations
• Vineyard spraying
• Specialty crop programs
• Precision agriculture missions
• Daily commercial deployments
• Fleet operations
• High-acreage contract work

Throughout these operations, tank cap seals are routinely exposed to:

• Compression on every fill cycle
• Direct chemical contact all day
• Concentrated product exposure
• Fertilizer residue and grit
• Cap over-tightening with gloved hands
• Pressure-washing and rinse cycles
• UV exposure at the fill point
• Heat cycling in summer conditions
• Airframe vibration
• Long commercial operating hours

Over time, this duty flattens, hardens, and cracks sealing rings — and a tired seal is a tank cap that leaks no matter how hard it's tightened.

The Spray Tank Cap Sealing Ring Set helps maintain:

• Leak-proof tank cap sealing
• Zero product loss at the fill point
• Protected airframe surfaces
• Full spray system integrity
• Fast, tool-free seal service
• A spare always in the kit
• Consistent maintenance standards
• Increased fleet readiness
• Maximum aircraft uptime
• Reliable commercial operation

For operators filling tanks all day, fresh cap seals are the cheapest chemical containment on the aircraft.

⚙️ Functional Purpose

The Spray Tank Cap Sealing Ring Set is designed to seal the tank cap interface on the DJI Agras T50, T40, T25, and T20P.

The component helps:

• Seal the tank cap against leaks and spills
• Compress evenly against the tank mouth
• Contain product through every flight attitude
• Withstand direct chemical contact
• Resist wear across thousands of fill cycles
• Replace flattened, hardened, or cracked rings
• Restore factory cap sealing in seconds
• Keep a spare seal in every field kit
• Maintain correct fitment across supported models
• Support preventative maintenance
• Reduce preventable leaks
• Reduce preventable downtime
• Increase fleet readiness
• Keep sealing inventory field-ready

A sealed tank starts at the cap — and the cap seals with the ring.

Fresh rings keep every gallon in the tank where it belongs, fill after fill, season after season.

A worn or damaged cap seal may contribute to:

• Leaking or weeping tank caps
• Chemical spills during flight maneuvers
• Product loss and waste
• Chemical residue down the airframe
• Contamination at the fill point
• Caps over-tightened to compensate
• Interrupted spraying missions
• Unexpected downtime
• Higher operating costs over time
• Reduced fleet reliability

Replacing worn rings restores the sealed fill point the spray system was engineered around.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Weeping or dripping at the tank cap
• Flattened or compressed ring profile
• Hardened, brittle ring material
• Cracks or splits in the ring
• Chemical swelling or deformation
• Rings that no longer seat evenly
• Caps requiring over-tightening to seal
• Chemical staining down the tank exterior
• Chunks or nicks from grit at the fill point
• Maintenance inspection findings
• Seasonal spray system rebuilds
• Fleet refurbishment projects
• Preventative pre-season replacement
• Long-term commercial wear

Common causes of seal failure include compression set from thousands of cap cycles, chemical attack swelling and softening the material, UV and heat hardening the rubber, grit at the fill point nicking the sealing face, and over-tightening crushing the profile — sealing rings are consumables by definition, and the two-ring kit exists because smart crews swap seals on schedule and keep the spare where the next fill happens.

For commercial operators, a fresh ring costs pennies against the chemical a leaking cap wastes every single tank.

💡 Why This Part Matters

Every fill on a commercial Agras ends the same way: the cap goes on, the seal compresses, and the operator trusts a ring of rubber to hold expensive chemical through takeoff, turns, and terrain-following passes. That trust gets renewed — or betrayed — dozens of times a day.

A tired seal doesn't announce itself. It weeps a little on the climb-out, streaks the tank on a hard turn, wastes a few ounces every mission — and by season's end the "small" leak has cost more in product than a lifetime supply of rings. The crews that never see that bill swap seals on schedule and keep the spare ring in the fill kit.

The Spray Tank Cap Sealing Ring Set helps maintain:

• Leak-proof fills, every fill
• Zero product waste at the cap
• Clean airframe surfaces
• A spare always on hand
• Seconds-fast seal service
• Factory fit and compression
• Professional fleet standards
• Increased aircraft uptime
• Reliable commercial performance
• Long-term operational confidence

Running tired seals, operators risk:

• Chemical weeping every mission
• Product waste that compounds daily
• Chemical-streaked airframes
• Contaminated fill points
• Interrupted missions
• Unexpected downtime
• Lost spraying opportunities
• Reduced return on investment

For practical, hardworking operators, the value is simple:

Protect the seal. Protect the tank. Protect the mission. Protect the season.

Professional DJI Agras operators understand that chemical containment is built one seal at a time. Keeping fresh sealing rings on hand means a ten-second swap at the fill point instead of a season of slow waste — and that difference is what separates a good season from a frustrating one.
