RaceFlux Straight AN Hose End to AN Male O-Ring Boss Fitting

The cleanest way to run braided hose into an ORB port: this hose end terminates directly in a male O-ring boss thread, so the line threads straight into oil coolers, thermostats, fuel logs, and pumps with no adapter fitting in between. One less connection means one less leak point, less weight, and more clearance.

The ORB end seals on a Viton O-ring against the port face — no thread sealant, no flare to gall, and it reseals reliably every time the line comes off. Like all RaceFlux D-series hose ends, it swivels for easy installation, uses a left-hand threaded socket that keeps the hose from backing out during assembly, and is machined from a single piece of 6061-T6 aluminum with zero welds or brazes.
