Fuel transfer couplings are critical components in fuel systems, enabling secure and leak-proof connections between fuel lines and tanks. They ensure efficient fuel transfer while maintaining system integrity under high pressure and varying temperatures. These couplings are designed for quick and easy installation, reducing downtime during maintenance or refueling operations.

Size: 1/2" to 4" nominal diameter

Grade: ASTM A105, ASTM A182, ASTM A350

Viscosity: Compatible with fuels ranging from 1 cSt (kerosene) to 500 cSt (heavy fuel oil)

Buoyancy: Typically neutral or slightly positive depending on material and design

Material: Stainless steel (304/316), carbon steel, aluminum, brass, or PTFE-lined for corrosion resistance

Pressure Rating: 150 psi to 3000 psi (varies by design and application)

Temperature Range: -40°F to 400°F (-40°C to 204°C)

Seal Type: Nitrile, Viton, or EPDM for fuel compatibility

Connection Type: Threaded, flanged, camlock, or quick-disconnect

Standards: API, SAE, ISO, MIL-SPEC compliance as applicable

Fuel Transfer Couplings and Fuel Systems may comply with maritime standards such as ISO 15859, ISO 15540, or other relevant industry-specific regulations. It is recommended to check the product specifications or consult the manufacturer for exact compliance details.
