AN To NPT 45 Degree -6 x 1/8in

The AN To NPT 45 Degree -6 x 1/8in adapter from Allstar Performance is a precision hydraulic and pneumatic fitting designed to bridge AN (Army-Navy) male connections with NPT (National Pipe Thread) male ports at a 45-degree angle. This adapter serves as an essential component in custom fuel systems, brake lines, and pressurized fluid applications where angled port orientation is critical to installation geometry. Available for purchase from TacticalSurplusUSA, it enables engineers and technicians to adapt existing hydraulic systems without extensive rework.

Manufactured from black anodized aluminum, this fitting combines lightweight durability with corrosion resistance—ideal for high-vibration environments and long-term reliability in demanding applications. The 45-degree bend reduces stress on hose assemblies by redirecting flow at optimal angles, lowering kink risk and extending hose service life. The -6 AN port accepts standard 3/8-inch hose, while the 1/8-inch NPT thread pattern accommodates common sensor ports, vent lines, and gauge connections. Anodized finish protects against oxidation and provides a professional appearance in engine bays and fluid systems.

This adapter is ideal for hot rod builders, race engine fabricators, and industrial hydraulic technicians who require compact angle fittings in tight spaces. Common applications include fuel system transitions, coolant bypass lines, and brake booster vacuum ports on custom or turbocharged engines. Installation requires standard wrench sizing for both AN and NPT threads; verify thread seal compatibility (PTFE tape or thread sealant recommended for NPT side) before assembly. Each unit ships ready to install, making it a reliable choice for restoration projects and performance builds.
