AN to NPT 90 Degree #16 x 3/4

The AN to NPT 90 Degree #16 x 3/4 adapter by Triple X Race Components is an essential hydraulic fitting for serious engine builders and high-performance fabricators who demand precision fluid routing. This 90-degree elbow adapter bridges the gap between AN (Army-Navy) hose ports and NPT (National Pipe Thread) manifold connections, eliminating the need for custom-machined solutions on custom cooling systems, fuel injection setups, and brake line configurations. Whether you're building a street rod, race engine, or complex custom application, this fitting ensures leak-free, reliable connections in tight engine bays where straight runs aren't feasible.

Built to Triple X Race Components' exacting standards, this adapter features a robust 90-degree geometry that redirects flow while maintaining full bore integrity for maximum flow rates without turbulence or pressure drop. The #16 AN port accommodates standard -16 hose (1 inch inner diameter), while the 3/4-inch NPT male thread integrates seamlessly into factory and aftermarket manifolds. Engineered aluminum or steel construction (per OEM specification) resists corrosion and thermal cycling, critical when mounted near exhaust runners or high-heat zones common in modified engines. The compact 90-degree design reduces fitting count and minimizes packaging footprint compared to dual 45-degree adapters.

This adapter is ideal for fabricators assembling late-model engine swaps, LS conversions, or prototype fuel systems where OEM port locations don't align with hose routing paths. Mechanics value this fitting for custom radiator plumbing, transmission cooler lines, and remote filter housing installations where thread mismatches would otherwise force costly rework. Installation requires standard wrenches and appropriate sealant tape or thread sealant on the NPT side; the AN port accepts industry-standard -16 hose with crimped or reusable fittings. Triple X's reputation for precision manufacturing ensures first-fit accuracy and durability across countless dyno sessions and competitive events.
