RaceFlux PTFE Straight Hose End Fitting, Steel

PTFE hose needs its own hose ends, and this is the workhorse of the RaceFlux T-series: a straight fitting for smooth-bore PTFE braided hose, built in zinc-plated steel with a brass compression ferrule that bites the PTFE liner for a secure, leak-free termination. The output side is a standard female 37-degree JIC swivel nut, so it threads onto any male AN fitting.

PTFE lines are the right call where rubber hose falls short — fuel systems where permeation matters, brake and clutch lines, and anywhere chemical resistance is critical — and these fittings are fully reusable when it's time to rebuild a line.
