The REDHORSE PERFORMANCE 10AN 45Deg Male Adapter connects -10 AN hose ends to 3/8-inch pipe thread ports at a 45-degree angle, making it a practical choice for fuel system builds, oil cooler lines, and custom cooling setups. Machined from 6061 T-6 aluminum with a black anodized finish, this fitting resists corrosion while keeping weight down in performance applications. The 45-degree orientation allows builders to route lines around tight clearances without kinking or stressing connections. We stock this adapter alongside our full adapter fitting inventory for complete plumbing solutions.
This adapter features CNC-machined construction from aerospace-grade 6061 T-6 aluminum, delivering precise thread cuts and consistent sealing surfaces across production runs. The male -10 AN flare side accepts standard 37-degree flare hose ends, while the male 3/8-inch pipe thread end seals into female ports on pumps, regulators, filters, and tank bungs. Black anodizing provides chemical resistance against fuels, oils, and coolants while maintaining a clean appearance in engine bays. The 45-degree bend angle splits the difference between straight and 90-degree fittings, giving fabricators flexibility when clearance to headers, chassis rails, or other components is limited.

Builders working on carbureted setups, electronic fuel injection conversions, dry sump oil systems, and transmission cooler plumbing will find this adapter handles the transition between AN-spec lines and pipe thread components. The fitting works equally well on street builds and dedicated track cars where vibration resistance and leak-free connections matter. Pair it with our braided hose options and -10 AN plugs to complete your fuel or oiling system with matched REDHORSE PERFORMANCE hardware throughout.
This adapter connects a male -10 AN (37-degree flare) fitting on one end to a male 3/8-inch pipe thread on the other end. The AN side accepts standard braided or rubber hose ends, while the pipe thread end screws into female ports on pumps, filters, regulators, and tanks.
Yes. The 6061 T-6 aluminum construction and black anodized finish are chemically compatible with gasoline, diesel, ethanol blends, and petroleum-based oils. Many builders use this adapter in fuel rails, carb inlet lines, oil cooler setups, and transmission cooler plumbing.
The 45-degree angle offers a middle-ground routing option when straight fittings create interference and 90-degree bends are too sharp. This angle helps avoid kinks in hose runs and reduces stress on connections in tight engine bay clearances.
The AN flare side seals metal-to-metal and does not need sealant. The pipe thread side typically requires PTFE tape or liquid thread sealant to achieve a leak-free seal, as pipe threads rely on interference fit rather than flare contact.
