AN To NPT 45 Degree -10 x 3/4in

The AN To NPT 45 Degree -10 x 3/4in adapter from ALLSTAR PERFORMANCE is a precision hydraulic and pneumatic fitting designed to connect AN (Army Navy) male ports to NPT (National Pipe Thread) male ports at a 45-degree angle. This adapter is essential for custom fuel, coolant, brake, and air line systems where space constraints or plumbing layout require angled connections rather than straight fittings. Whether you're building a high-performance engine bay, restoring a classic vehicle, or assembling industrial hydraulic systems, this fitting eliminates the need for bulky elbows and reduces stress on adjacent components.

Constructed from lightweight aluminum and finished with black anodized coating, the AN To NPT 45 Degree adapter provides excellent corrosion resistance while maintaining low weight—critical for performance and racing applications. The -10 AN port accepts standard -10 hose and fittings (5/8-inch hose ID), while the 3/4-inch NPT male side threads into NPT ports found on blocks, manifolds, and aftermarket components. The 45-degree angle design improves flow characteristics compared to 90-degree configurations, reduces turbulence, and allows tighter packaging in cramped engine compartments where clearance is a premium.

This fitting is ideal for engine builders, fabricators, and enthusiasts working with LS engines, small-block Chevrolets, and other platforms where custom cooling or fuel line routing is necessary. Installation requires no special tools—simply thread the NPT end into the port using appropriate thread sealant and torque the hose end to spec. The compact 2 x 1.4 x 4.1-inch profile fits tight spaces where traditional fittings cannot, making it a go-to choice for race cars, hot rods, and precision hydraulic assemblies.
