RaceFlux AN O-Ring Boss to AN Male Flare Adapter Fitting
RaceFlux AN O-Ring Boss to AN Male Flare Adapter Fitting
The RaceFlux O-ring boss to AN male flare adapter is the workhorse fitting for getting out of ORB ports on fuel rails, pumps, regulators, and oil system components and into standard AN plumbing. The straight-thread ORB side seals on a Viton O-ring instead of tapered threads, so there's no thread sealant, no over-tightening to chase a leak, and no debris risk in your fuel or oil system.
The low-profile design runs shorter than standard straight-thread O-ring fittings, buying you extra clearance in tight engine bays, and the black anodized finish gives a cleaner look than traditional red and blue hardware.
Key Features
- Male ORB (straight thread with Viton O-ring) to male AN / JIC 37-degree flare

- Port-compliant with SAE J1926-1 / MS16142 and SAE AS5202 / MS33649
- Reusable, with no thread sealant required on the ORB side
- 1-year manufacturer's warranty against defects
