#6 To #6 An Port Adapter

The #6 to #6 AN Port Adapter is a precision fluid connection component engineered for high-performance hydraulic and fuel system applications. Designed for technicians, mechanics, and performance enthusiasts who demand reliability in critical fluid transfer lines, this straight adapter bridges two 6 AN (AN6) male ports seamlessly. Whether you're assembling a custom fuel system, upgrading cooling lines, or fabricating a hydraulic setup, this adapter provides the secure, leak-free connection required in demanding automotive and industrial environments.

Manufactured by EARLS, a trusted leader in fluid system fittings, this adapter features aluminum construction with blue anodized finish for corrosion resistance and durability. The O-ring sealed design ensures positive sealing without additional thread sealant, reducing installation complexity while maximizing reliability under pressure. The straight configuration allows for efficient inline connections where two 6 AN male threads must mate directly, making it ideal for applications where space and flow path efficiency are paramount. Weighing just 0.02 lbs with compact dimensions of 1.15 x 0.95 x 3.1 inches, this fitting integrates seamlessly into tight engine bays and custom installations.

This adapter is essential for anyone building or modifying fuel injection systems, turbo boost lines, transmission coolers, or aftermarket cooling circuits. The 6 AN port size accommodates high-flow applications at elevated pressures, making it suitable for supercharged and turbocharged engines where standard fittings fall short. Installation is straightforward—simply thread the male connectors into the adapter ports and tighten to secure. The O-ring seal eliminates guesswork and ensures compatibility with standard 6 AN hose fittings and port sizes, guaranteeing that your system performs reliably from first startup through years of service.
