#6 Union Fitting

The #6 Union Fitting from FRAGOLA is a straight adapter designed to connect two 6 AN male ports with reliable, leak-free performance. This fitting is engineered for fluid systems in high-performance vehicles, racing applications, and custom hydraulic or fuel line assemblies where secure port-to-port connections are critical. The union fitting design allows for quick disconnect and reconnect capability, making it ideal for technicians and enthusiasts who regularly service or modify fluid delivery systems.

Constructed from aluminum and finished in blue anodized coating, this adapter provides excellent corrosion resistance while maintaining lightweight construction essential for performance applications. The straight-through design eliminates flow restrictions and maintains full 6 AN port compatibility at both ends, ensuring pressure rating consistency throughout the assembly. Blue anodizing not only protects against oxidation but also offers high visibility for system identification and maintenance documentation in complex plumbing layouts.

This fitting is ideal for fuel system builders, transmission cooler installations, brake fluid upgrades, and any application requiring two male 6 AN connections to be joined. Its compact dimensions (1.55 x 1.25 x 4.25 inches) allow installation in tight engine bays or confined spaces common in race cars and street rods. The lightweight design at just 0.02 lbs makes it suitable for weight-conscious builds while delivering durability demanded by high-pressure fluid systems operating under demanding track or street conditions.
