Quick Disconnect Alum -4 Kit

The ALLSTAR PERFORMANCE Quick Disconnect Aluminum -4 Kit (ALL50213) is a complete fluid coupling system designed for high-pressure hydraulic and fuel line applications in performance vehicles, race cars, and off-road equipment. This kit supplies both male halves with 4 AN (AN4) port threads, engineered for seamless connections where quick-disconnect fittings are essential for maintenance, fluid servicing, or modular system assembly.

Constructed from aluminum and finished in black anodize, this quick disconnect AN4 male coupling kit provides corrosion resistance and lightweight performance critical in competitive and extreme-use environments. The 4 AN specification indicates a nominal 1/4-inch port diameter, standard across the motorsports and aerospace fluid systems industry. Black anodized aluminum reduces weight compared to steel alternatives while offering protection against salt spray and moisture exposure common in track, marine, and desert applications. The kit's compact footprint—measuring 4.1 x 0.9 x 7.05 inches and weighing just 0.12 lbs—makes it ideal for installation in space-constrained engine bays and custom fluid routing configurations.

This fitting kit addresses the needs of race teams, hot rodders, drag racers, and off-road enthusiasts who require reliable, quick-connect fluid systems for nitrous oxide delivery, fuel supply reconfiguration, or cooling line management. The quick-disconnect design eliminates spillage during coupling or decoupling operations, reducing downtime and fluid waste on the track or workshop bench. AN4 fittings represent the industry standard for moderate-flow hydraulic and fuel applications, balancing flow capacity with compact coupling geometry—making this kit suitable for auxiliary fuel cells, intercooler loops, and pressure-fed lubrication systems in high-performance builds.

ALLSTAR PERFORMANCE is a recognized supplier of performance plumbing and fuel system components to the racing community, with an established reputation for manufacturing reliable AN fittings and quick-disconnect couplers. This AN4 male kit integrates into any system already using standard -4 quick-disconnect female halves, ensuring compatibility across modular and evolving performance platforms.
