Male -6AN to Male 1/4in NPT 90 Degree Fitting

The Male -6AN to Male 1/4in NPT 90 Degree Fitting from Vibrant Performance is an essential component for custom fuel system, coolant line, and hydraulic brake modifications on performance vehicles. This 90-degree adapter bridges AN (Army-Navy) threaded ports to NPT (National Pipe Thread) applications, making it invaluable when connecting aftermarket fuel rails, turbo feed lines, catch cans, and remote oil cooler setups where port orientations don't align. Whether you're tuning a street car, building a race engine, or upgrading to a standalone fuel management system, this fitting ensures reliable, leak-free connections in tight engine bay configurations.

Manufactured by Vibrant Performance, a trusted name in high-flow fuel system components and plumbing solutions, this fitting features precision-machined aluminum construction with the 90-degree angle geometry that allows you to route hoses and hard lines around obstructions without kinking or crushing. The -6AN male thread accommodates standard -6 hose fittings (3/8-inch hose ID), while the 1/4-inch NPT male port accepts NPT-threaded component ports found on many OEM and aftermarket fuel pumps, thermostatic switches, and pressure sensors. The compact 3.54-inch length and lightweight 0.07-pound design mean minimal bulk in confined spaces, and the angled configuration reduces bending stress on hard lines and braided hoses compared to straight fittings.

This adapter is ideal for builders working on fuel system upgrades, EFI retrofits, and turbo installations where existing port locations require directional changes. It's commonly used in custom fuel rails, intake manifold coolant bypass circuits, and vacuum-to-hydraulic brake conversions on modified and vintage vehicles. Always verify both your AN fitting size (-6 = 3/8-inch hose) and NPT port size (1/4-inch) match your application, and consider using thread sealant or PTFE tape on the NPT male threads to prevent weeping on dynamic systems. Pair this fitting with quality braided hose or hard-anodized aluminum tubing for maximum reliability under boost and sustained high-load driving.
