-6an Swivel Gauge Adapter

The -6AN Swivel Gauge Adapter from Nitrous Oxide Systems is a precision fitting designed for nitrous oxide system installations and fuel pressure monitoring applications. This adapter bridges the gap between your gauge port and AN-line plumbing on your fuel or nitrous system, making it essential for builders who need accurate, real-time pressure readings during tuning and diagnostics. Whether you're setting up a street performance build or dialing in a track-focused nitrous system, this compact adapter ensures your instrumentation connects reliably to your distribution block or manifold.

Constructed from lightweight aluminum and finished in blue anodize for corrosion resistance, the -6AN Swivel Gauge Adapter features a straight-flow design that minimizes turbulence and pressure loss in your line. The fitting transitions from a 6 AN female connection on one end to a 6 AN male connection on the other, with a dedicated 1/8 inch NPT gauge port that accepts standard aftermarket pressure gauges. The swivel design on the main AN connections eliminates stress on hose fittings during installation and vibration cycles, reducing fatigue cracking and micro-leaks that plague rigid setups.

This adapter works across Nitrous Oxide Systems' complete product ecosystem and fits any fuel or nitrous distribution block equipped with a standard 1/8 NPT gauge port. Mechanics and tuners running carbureted or EFI systems with nitrous oxide kits, as well as those monitoring fuel pressure on high-flow fuel systems, will find this fitting indispensable for maintaining system visibility. The 0.08 lb weight and compact 2.95 x 1.05 x 3.5 inch profile make it easy to position in tight engine bays, and the blue anodized finish coordinates with OEM and aftermarket fuel system components for a professional appearance.
