The Redhorse Performance 8AN 45-Degree Male Adapter connects -08 AN flare fittings to 1/2-inch tapered pipe thread ports at an optimized angle for tight engine bay routing. Machined from 6061-T6 aluminum with a black anodized finish, this adapter serves builders who need to bridge two common thread standards without stacking multiple fittings or running awkward hose angles. The 45-degree configuration reduces stress on hose assemblies while maintaining clean aesthetics under the hood. We stock this adapter for fuel system builds, oil cooler installations, and custom cooling circuits where mixed-thread integration is required.
Redhorse machines this adapter on CNC equipment to achieve precise thread engagement on both ends. The -08 AN male side features the standard 37-degree flare angle that seals against AN female fittings, while the 1/2-inch male pipe thread end uses tapered threads for metal-to-metal or tape-sealed connections. The 6061-T6 aluminum construction keeps weight minimal without sacrificing durability in pressurized fluid systems. Black anodizing provides corrosion resistance and a subdued appearance that matches most aftermarket engine components. For builders working on fuel injection systems, turbo oil feed lines, or hydraulic circuits, this adapter eliminates the need for additional 90-degree fittings and extra hose length that complicate routing in cramped spaces.
This fitting suits builders assembling fuel rails, remote filter setups, or catch can plumbing where a straight adapter would force hoses into sharp bends. The 45-degree angle splits the difference between straight and 90-degree options, often providing the cleanest path through crowded engine bays. Pair it with braided stainless or nylon-braided AN hose assemblies for a complete fluid transfer solution. We carry a full selection of parts and accessories for custom automotive builds, along with the multi-tools and support gear you need for shop work and field service.

This adapter joins a -08 AN male fitting with a 37-degree flare to a 1/2-inch male tapered pipe thread port. The AN side uses straight threads that seal against a flared surface, while the pipe thread side seals through thread taper or thread sealant tape.
Yes. The 6061-T6 aluminum and black anodized finish are compatible with common automotive fuels including gasoline and E85 blends. Many builders use this adapter to connect AN fuel lines to fuel rails, filters, or regulators with 1/2-inch pipe thread ports.
A 45-degree angle often provides the best routing compromise in tight engine bays. It reduces hose stress compared to sharp 90-degree bends while avoiding the clearance issues that straight adapters can create when hoses must change direction immediately.
The AN flare end seals metal-to-metal against the mating AN female fitting and does not require sealant. The pipe thread end typically requires PTFE tape or liquid thread sealant to achieve a leak-free seal, as pipe threads rely on taper interference.
