AN To NPT Swivel 90 Deg -8 x 3/8in

The AN To NPT Swivel 90 Deg -8 x 3/8in adapter from ALLSTAR PERFORMANCE is a precision-engineered fitting designed for high-performance fuel, oil, coolant, and pneumatic systems in race cars, hot rods, and modified street vehicles. This 90-degree angle adapter bridges two industry-standard port types—8 AN (dash-8) male ports and 3/8 inch NPT (National Pipe Thread) male ports—making it an essential solution when connecting aftermarket fuel rails, turbo coolers, transmission coolers, or boost control systems to factory or custom manifold threaded bungs. Built for reliability under pressure and vibration, this swivel fitting prevents line misalignment stress and eliminates the need for bulky elbows and extra hose runs.

Manufactured from aluminum and finished in black anodize, the AN To NPT Swivel 90 Deg -8 x 3/8in delivers corrosion resistance and a professional appearance in engine bay installations. The swivel design—a hallmark of quality hose fittings—allows the hose end to rotate freely relative to the port threads, reducing installation torque stress and protecting both the fitting and the port from cracking or stripping during assembly and thermal cycling. The anodized finish protects against oxidation and brake fluid or fuel contamination, critical for longevity in performance applications. Weighing just 0.12 lbs and measuring 4 inches in length, this compact adapter fits tight engine compartments without requiring major plumbing redesigns.

Builders and mechanics choose this fitting for turbocharger supply lines, fuel pressure gauge installations, aftermarket fuel system upgrades, and custom coolant loops where NPT-threaded block ports must mate to AN braided hose setups. The 90-degree angle is ideal when space is limited or when line routing must clear exhaust manifolds, intake runners, or other engine components. Installation requires standard AN wrench sizes on the hose barb side and a pipe wrench or NPT socket on the threaded port—a straightforward job for any technician familiar with fuel system or cooling system modifications. Ensure proper PTFE thread tape application to the NPT side and verify port thread pitch before ordering to guarantee correct fit in your specific application.
