Coaxial Dual-Channel Flow Architecture

The FastFuel Pro™ connector is engineered around a patented coaxial geometry: a central bore delivers pressurized fuel while the surrounding annular channel continuously recovers vapors — achieving closed-loop, zero-emission refueling without additional hardware.

INNER FUEL CHANNEL (CORE TUBE)
Precision-molded PEEK. Amber channel delivers pressurized fuel at up to 50 GPM.
OUTER VAPOR RECOVERY ANNULUS
Blue annular channel continuously routes vapor emissions away from the seal interface — Stage II compliant, zero pressure entrapment.
Closed-Loop Flow Stage II Vapor Zero Emission Push-to-Connect MIL-DTL-58063

Connector System

Male and female connectors designed for fully autonomous, zero-crew engagement. Ball latch locking, 360° evaluation channels, and front-load cartridge replacement — all in a MIL-grade package.

Male and Female Connector System
FFP-QDC-3232-M / F
Male & Female Connectors

Hardened stainless steel ball latches provide vibration-resistant locking. Push-to-connect — no rotation required. Dust caps tethered, included.

Replaceable Cartridge Core Components
FFP-CC-3232 PEEK CORE
Cartridge Core Components

PEEK structural sleeve, FKM energized lip seals (inner & outer), precision bore core tube, inner support ring, and end retainer cap — all field-replaceable as a single modular unit.

Female Receptor Port
FFP-RPR-3232
Female Receptor Port

Aerospace aluminum shell rigidly mounted to the tank bulkhead. 120° locking detachable cap. Tool-less front maintenance with composite Viton seals for wide tolerance performance.

Secure Connection. Field Service in Seconds.

Two independent mechanisms — push-to-connect ball latch locking for mating, and 120° rotation front cap nose for cartridge-only replacement. No tools. No downtime.

CARTRIDGE REPLACEMENT PROCESS (TOOLLESS)

1

Unlock Front Cap Nose

Rotate 120° counterclockwise to unlock and pull straight off.

2

Remove Spent Cartridge

Pull the PEEK cartridge core straight out. No tools required.

3

Insert New Cartridge

Push the new FFP-CC-3232 cartridge core in until fully seated.

4

Reinstall Front Cap Nose

Align and push the front cap nose on, then rotate 120° clockwise to lock.

5

Verify via 360° Channels

Visually confirm full engagement, seal compression, and clean flow path — no gaps or misalignment.

Connector Mating — No Rotation Needed

Push male into female until ball latches automatically engage. Connection is locked, sealed, and ready. The 120° rotation ONLY applies to front cap nose removal for cartridge service.

Front-Load Replacement Process

Legacy SPR Infrastructure Interoperability

FastFuel Pro™ integrates directly with existing MIL-DTL-58063 single-point refueling nozzles via the Tactical Transition Adapter. No modification to field equipment. Transforms single-stream supply into dual-channel closed-loop flow at the tactical edge.

Legacy SPR Infrastructure Interoperability
🔧

Zero Field Modification

Direct interface with existing D-1/D-2 style MIL-DTL-58063 standard nozzles. No changes to existing infrastructure required.

🔄

Dual-Channel Conversion

The 6061-T6 aluminum Tactical Transition Adapter converts single-bore supply into coaxial fuel + vapor recovery flow at the point of connection.

🛡️

Integrated Vapor Management

Local Stage II vapor venting and filtration port manages returned vapor at the tactical edge — safe, compliant, no external equipment needed.
