#6 Male AN Union

The #6 Male AN Union from Triple X Race Components is a straight adapter fitting designed to connect two 6 AN male ports with secure, leak-free performance. Manufactured from aluminum and finished in black anodize, this compact coupling is engineered for high-pressure hydraulic and fuel system applications where reliability and corrosion resistance are non-negotiable.

AN (Air Force-Navy) fittings are the industry standard for aerospace, automotive, and motorsports fluid transfer systems because they deliver consistent thread form and repeatability. The 6 AN designation indicates a nominal outside diameter of 0.750 inches, with male ports at both ends allowing direct connection without adapters. The black anodized aluminum construction provides excellent corrosion protection while maintaining a lightweight profile—critical in racing applications where every ounce matters. The straight configuration enables direct coupling in tight engine bay installations where offset or elbow fittings won't fit.

This fitting is purpose-built for high-performance racing, vintage drag competition, fuel injection systems, and custom hydraulic setups where OEM connectors are replaced with performance-grade components. Triple X Race Components specializes in precision race hardware, and this union meets the tight tolerances required to prevent leakage under pressure spikes common in supercharged and turbocharged engines. Installation requires standard AN wrench sizing and is compatible with all industry-standard AN hose and port combinations.

For buyers assembling or restoring fuel systems, hydraulic cooling lines, or transmission cooler circuits, individual AN fittings allow precise system configuration without purchasing oversized kits. The compact 2 x 0.75 x 2.75 inch dimensions and 0.02 lb weight ensure minimal impact on layout or weight distribution.
