The REDHORSE PERFORMANCE 823-08-04-2 is a 45-degree adapter that mates a -08 AN male hose end to a 1/4-inch Npt male port, giving builders a clean way to route fuel, oil, coolant, or brake lines around tight spaces. It's aimed at racers and custom automotive builders who need to change thread standards and redirect a line in one fitting. The angled body keeps hose runs short and reduces strain where a straight adapter would force an awkward bend, which matters in cramped engine compartments. You'll find it alongside the rest of our fittings, hoses, and valves selection.
This adapter is CNC machined from 6061-T6 aluminum, a grade chosen for thread strength under the pressure and vibration of high-performance fluid systems. The black anodized finish is color-consistent and hand polished, so the fitting holds its appearance in exposed engine-bay routing. The male-to-male configuration combines a -08 AN flare on one side, which seals against an AN hose end, with a tapered 1/4-inch pipe thread on the other for sealing into a threaded port. The 45-degree bend lets you turn a line without adding a separate elbow, cutting down on connection points and potential leak paths. Redhorse rates the fitting as race tested and backs it with a lifetime warranty against manufacturing defects. Pair it with matching -8 straight hose ends for a complete run.
Reach for this adapter when an AN hose has to land on a pipe-threaded port and the geometry needs to turn at 45 degrees, common at fuel rails, regulators, oil coolers, and pump inlets. Use thread sealant or tape on the pipe-thread side and torque the AN flare against its mating hose end. If you're plumbing a full system, browse our -8 plugs and the broader adapter category to finish the build. Questions on sizing? Reach out and we'll help you match the right hose end and port combination.
It connects a -08 AN male hose end to a 1/4-inch male pipe thread port. The -08 AN side seals against an AN hose end using its 37-degree flare, while the 1/4-inch pipe-thread side threads into a tapered port. The 45-degree bend lets you change direction without a separate elbow fitting.
The fitting is CNC machined from 6061-T6 aluminum and finished in black anodizing. Redhorse chose 6061-T6 for its thread strength under the pressure and vibration found in high-performance fuel, oil, and coolant systems. The anodized coating is color-consistent and hand polished.
The 1/4-inch pipe-thread side is a tapered thread that requires sealant or thread tape to seal properly against the port. The -08 AN side seals mechanically through its flare against the mating hose end and does not need sealant. Apply sealant only to the pipe-thread end.
It's designed for high-performance fluid systems including fuel lines, oil lines, coolant, and brake line routing in racing and custom automotive builds. The 45-degree angle is useful in tight engine compartments where a straight fitting would force a sharp hose bend.
Yes. Redhorse Performance backs this adapter with a lifetime warranty against manufacturing defects, per manufacturer specifications. The fitting is described as race tested for high-performance applications.
