The Redhorse Performance 4AN 90-degree male adapter to 3/8 in. Npt male is a fuel and fluid plumbing fitting that converts a -4 AN line to a 3/8 in. pipe-thread port at a right angle. Builders running braided systems use it to tie into gauge bungs, regulators, pumps, and factory pipe-thread ports where space is tight and a straight fitting would bind a hose. Machined and finished in black anodized aluminum, it carries part number 822-04-06-2 and ships individually. It belongs in our wider catalog of AN adapters for street, race, and shop builds.
This adapter is machined from 6061-T6 aluminum with a black anodized finish that resists corrosion and matches the look of black hose ends. The -4 AN side uses a 37-degree flare seat that seals against an AN swivel hose end without sealant, while the 3/8 in. pipe-thread side threads into a tapered port and should be sealed with thread sealant or PTFE tape rated for fuel. The 90-degree body routes the line cleanly away from the port, which keeps hose runs short and avoids kinking near pumps, filters, and regulators. Redhorse Performance backs the part with a lifetime warranty against manufacturing defects, per the manufacturer's stated terms. Pair it with matching -4 hose ends and braided line for a complete circuit.
Reach for this fitting when you need to connect a -4 braided line to a 3/8 in. pipe-thread fuel rail, regulator, oil port, or sender bung without forcing the hose into a hard bend. The right-angle design is a common pick for fuel systems, turbo oil feeds, and gauge plumbing in engine bays where clearance is limited. It works alongside unions, tees, and plugs from the same product family. Browse the full fittings, hoses, and valves selection to match thread sizes and finishes across your build, and check our -4 union fittings when you need to extend a run.
It connects a -4 AN line to a 3/8 in. pipe-thread male port at a 90-degree angle. The AN side mates to a -4 swivel hose end, and the pipe-thread side threads into a tapered port such as a fuel rail, regulator, gauge bung, or sender boss.
The 3/8 in. pipe-thread side is tapered and should be sealed with a fuel-rated thread sealant or PTFE tape. The -4 AN side uses a 37-degree flare seat and seals metal-to-metal against an AN hose end, so it does not require sealant.
It is machined from 6061-T6 aluminum with a black anodized finish that resists corrosion and matches black AN hose ends and fittings, according to manufacturer specifications.
This adapter ships individually under part number 822-04-06-2. If you need more than one for a build, add the quantity you require at checkout.
The 90-degree -4 AN to 3/8 in. pipe-thread design is commonly used in fuel delivery, turbo oil feed, and gauge plumbing. Match it with proper -4 hose and hose ends rated for your system pressure and fluid.
