Adapter Fitting -3 To 1/8 NPT 45 Degree

The Adapter Fitting -3 To 1/8 NPT 45 Degree from ALLSTAR PERFORMANCE is a precision hydraulic and pneumatic connector designed for high-pressure applications where port alignment and space constraints demand angled solutions. This 45-degree adapter bridges AN-3 male connections to 1/8-inch NPT male ports, making it essential for fuel systems, cooling circuits, and custom fluid routing in race cars, hot rods, and performance engines. Whether you're fabricating a custom fuel cell installation or relocating coolers and accumulators, this fitting eliminates the need for multiple components and ensures leak-free operation under demanding conditions.

Manufactured from steel and finished with zinc oxide plating, the adapter combines corrosion resistance with durability in both street and competitive environments. The 45-degree geometry allows tubing or hoses to approach the port at an angle, reducing installation hassle and protecting adjacent components from unwanted contact or vibration damage. The AN-3 male end accepts standard -3 hose fittings or solid tubing adapters, while the 1/8 NPT male threads provide a secure connection to female NPT ports commonly found on manifolds, gauges, sensors, and pressure relief valves. This configuration eliminates the need for multiple elbows and extensions, reducing pressure drop and simplifying system diagnostics.

Professional engine builders and restoration specialists rely on the Adapter Fitting -3 To 1/8 NPT 45 Degree for custom fuel, oil, coolant, and brake system plumbing. It works seamlessly with fuel injection systems, turbo oil supply lines, transmission coolers, and auxiliary heating circuits where direct 90-degree connections would create clearance conflicts or stress on adjacent lines. Installation requires hand-tightening with a wrench on both the AN and NPT ends; Teflon tape or thread sealant is recommended on the NPT side to ensure a sealed connection. The compact 3.5-inch length and minimal weight make this adapter ideal for tight engine bays where every inch of routing space matters.
