6AN 45Deg Male Adapter to 1/8in NPT Male Blue

The 6AN 45Deg Male Adapter to 1/8in NPT Male Blue from REDHORSE PERFORMANCE is a precision hydraulic and pneumatic fitting engineered for high-flow applications where space and angle constraints demand a compact solution. This 45-degree adapter bridges AN (Army Navy) sized connections to National Pipe Taper (NPT) threaded ports, making it essential for custom fuel systems, brake lines, coolant circuits, and pneumatic control assemblies. Technicians and performance builders rely on this fitting type when standard straight adapters won't fit tight engine bays or complex manifold layouts.

Manufactured from aluminum and finished in blue anodized coating, the 6AN 45Deg Male Adapter combines lightweight construction with corrosion resistance and visual identification on color-coded fluid systems. The 45-degree angle geometry reduces turbulence and strain on connected hoses compared to multiple elbows, improving flow efficiency while lowering installation stress on adjacent components. The male-to-male configuration (6 AN male end connecting to 1/8 in NPT male port) allows direct integration into female-threaded receptacles on pumps, manifolds, gauges, and remote reservoirs without intermediate couplers.

This adapter suits EFI fuel system builders, hot rod plumbing, racing hydraulic brake upgrades, and custom air suspension installations where NPT porting on components must accept AN-sized hose fittings. Installation requires thread-sealant (PTFE tape or anaerobic compound) on the 1/8 in NPT male threads to ensure leak-free sealing under pressure. The compact 2.85 x 1.1 x 3.85 inch footprint and 0.05 lb weight make it ideal for weight-critical or space-constrained engine compartments, while the REDHORSE 823 Series design standard ensures compatibility with aftermarket fuel rails, coolant blocks, and vacuum/boost distribution blocks across the performance automotive market.
