The Vibrant Performance -8AN Female to 3/8inNPT Male Swivel 90 Degree adapter (MPN 11387) connects an -8AN female swivel end to a 3/8in male pipe thread, with a 90-degree bend that lets builders route hose around tight engine bays without kinking. It's aimed at anyone plumbing custom fuel systems, turbo oil feeds, oil coolers, or remote filter setups who needs to bridge AN flare hardware and tapered pipe-thread ports. The swivel design means the -8AN hose end tightens independently of the pipe-thread side, so you can clock the elbow and seal both connections without twisting the hose. Browse the full swivel fitting selection for matching ends.
The female -8AN side uses the standard 37-degree flare seat that mates to any -8AN male hose end or hard line. The opposite end carries a 3/8in tapered male pipe thread that seals against a matching female port using thread sealant or PTFE tape. Because the AN connection swivels, you set the angle of the elbow first, thread the pipe side into the manifold or fitting, then seat the hose end and torque it down with the swivel taking up the rotation. That keeps the hose from corkscrewing as you tighten. Pair this elbow with a matching -8AN straight hose end and the appropriate braided hose to complete a clean run from port to component.
Reach for this 90-degree adapter when a fuel rail return, turbo drain, regulator port, or oil cooler line needs to turn sharply right at the connection point and a straight fitting would force the hose into a hard bend. The swivel makes final assembly far easier in cramped spaces where you can't rotate the whole hose. It works equally well on race builds, street performance cars, and off-road fuel and cooling plumbing. When you're spec'ing a complete system, check our broader fittings, hoses, and valves selection for unions, tees, caps, and the hose ends that finish the job.
It joins an -8AN female swivel hose end to a 3/8in male tapered pipe thread port. The 90-degree bend turns the line sharply at the connection, which is useful where a straight fitting would force the hose into a tight radius.
The -8AN side rotates independently of the pipe-thread side. You thread the pipe end into the port first, then seat and torque the hose end without twisting the hose. In a packed engine bay, that makes final assembly much simpler.
Yes. The 3/8in male pipe thread is a tapered thread that seals on the threads themselves, so use a fuel-rated thread sealant or PTFE tape on that side. The -8AN flare side seals on the 37-degree cone and needs no tape.
Any -8AN male hose end works on the female swivel. Match it to your hose type and size, then run -8AN braided line to the component. Our hose-end and hose listings cover the matching pieces for a complete run.
