Product Description
The 20-3940-e003701 is a PTFE aircraft fluid line for fuel transfer between airframe system components. This hose assembly routes fuel safely through engine feed systems, fuel selectors, and tank interconnects on general and corporate aviation aircraft. Constructed from polytetrafluoroethylene (PTFE) tubing with AN/MS flare fittings, it resists fuel degradation and maintains integrity under pressure cycling.
Installation requires proper 37-degree flare fitting torque, clamp placement per specifications, and pressure testing to verify leak-free operation before flight.
