The REDHORSE PERFORMANCE 6AN 45Deg Male Adapter bridges two common but incompatible thread standards in automotive fluid systems. This 823 Series fitting connects a -6 AN male thread to a 1/2 inch pipe thread male connection at a 45-degree angle, giving builders the routing flexibility needed in tight engine bays. Designed for fuel, oil, and hydraulic plumbing applications, this adapter serves enthusiasts and professional fabricators who demand leak-free connections between AN flare fittings and standard pipe thread ports. Browse our complete adapter fitting collection for additional thread combinations.
REDHORSE PERFORMANCE machines this adapter from aluminum with a black anodized finish that resists corrosion and matches other components in the 823 Series lineup. The CNC machining process ensures precise thread engagement on both ends—the -6 AN side uses a 9/16-18 UNF thread with a 37-degree flare seal, while the pipe thread side employs a tapered 60-degree seal geometry. The hand-polished surfaces minimize flow turbulence through the 45-degree bend. This color-matched construction integrates cleanly with other black AN fittings, maintaining a professional appearance in show-quality builds. The aluminum construction keeps weight down compared to steel alternatives while handling the pressures common in street and track applications.
Install this adapter where space constraints prevent straight-line routing between AN hose assemblies and pipe-threaded components like fuel pumps, oil cooler sandwich plates, or hydraulic reservoirs. The 45-degree angle often provides clearance past headers, frame rails, or accessory brackets that would interfere with straight or 90-degree fittings. Pair with compatible 6AN union fittings or explore our fittings, hoses, and valves category for hose ends, caps, and additional adapter configurations to complete your custom fluid system build.
This adapter connects a -6 AN male fitting (9/16-18 UNF thread) to a 1/2 inch National Pipe Thread male connection. The AN side seals via a 37-degree flare, while the pipe thread side uses tapered threads with thread sealant for a leak-free connection.
Yes, REDHORSE PERFORMANCE designs the 823 Series fittings for automotive fluid systems including fuel, oil, and hydraulic applications. The aluminum construction and anodized finish resist corrosion from common automotive fluids and fuels.
A 45-degree angle provides routing flexibility in confined spaces where straight fittings cannot clear obstacles and 90-degree bends would create excessive restriction or stress on hose assemblies. This angle often works around headers, frame rails, and engine accessories.
Yes, pipe thread connections require thread sealant tape or paste to create a proper seal. The tapered pipe threads do not seal mechanically like AN flare fittings—apply appropriate sealant before installation and tighten to specification.
