90 Deg. #6 > 3/8 Npt Adp

The 90 Degree #6 to 3/8 NPT Adapter from Earl's represents a critical hydraulic fitting solution for automotive fluid systems, fuel delivery, and brake line applications. Whether you're building a custom fuel injection setup, routing power steering lines, or integrating aftermarket cooling systems, this adapter bridges incompatible port sizes with precision engineering. Mechanics and performance enthusiasts rely on Earl's fittings to eliminate leaks and maintain system integrity under pressure.

This adapter features a 90-degree elbow design that redirects fluid flow at a right angle, allowing tight routing in cramped engine bays where straight hose runs aren't feasible. The #6 JIC (SAE) inlet connects to larger-diameter hoses or fittings, while the 3/8 NPT (National Pipe Thread) outlet adapts to standard port configurations found on fuel rails, pressure gauges, and manifold blocks. Earl's precision manufacturing ensures consistent thread pitch and seal surfaces, reducing vibration-induced loosening and maintaining repeatable pressure ratings across thermal cycling and high-vibration environments typical of modified vehicles.

Street tuners, drag racers, and restoration specialists benefit most from this adapter when upgrading fuel systems, installing boost-referenced fuel pressure regulators, or retrofitting gauge bundles into legacy engine bays. The compact 1.95 x 0.85 x 2.65-inch profile and lightweight 0.06-pound design won't add clutter or bulk to an already crowded compartment. Installation requires only a wrench and thread-sealant tape for NPT connections; verify your hose size and port thread type before ordering to ensure seamless integration with your existing hydraulic architecture.
