Adapter Union Fitting #6 Male

The Adapter Union Fitting #6 Male is a precision straight adapter designed to connect two 6 AN male ports in high-pressure fluid systems. This fitting is essential for hydraulic, fuel, and coolant lines where secure, leak-free connections are non-negotiable. Whether you're assembling a custom fuel system, restoring a classic vehicle, or building a high-performance engine bay setup, this Russell adapter provides the reliability and durability demanded by professionals and enthusiasts alike.

Constructed from aluminum and finished in blue anodize, this male-to-male union fitting delivers both corrosion resistance and lightweight performance. The straight configuration eliminates unnecessary bends, reducing turbulence and pressure drop while simplifying installation in tight engine compartments. Russell's precision engineering ensures exact thread specifications on both ends, creating a metal-to-metal seal when paired with AN-compatible hoses and fittings—critical for maintaining system integrity under high vibration and temperature fluctuations. The compact design, measuring 1.65 x 1.4 x 5.8 inches and weighing just 0.05 lbs, allows seamless integration into space-constrained applications.

Ideal for automotive technicians, fabricators, and performance builders, this adapter works seamlessly with all AN-spec hoses, clamps, and components rated for 6 AN connections. Installation requires minimal tools—simply thread both ports hand-tight, then use a wrench to ensure a secure fit without over-tightening. For maximum longevity, pair with quality AN hoses, proper PTFE tape or sealant on threaded connections, and periodic inspection to verify integrity. This single fitting is sold individually, allowing you to purchase exactly what your system demands.
