6AN Male to 3/8in Tube Adapter Clear

The 6AN Male to 3/8in Tube Adapter Clear from REDHORSE PERFORMANCE is a precision straight adapter fitting engineered for high-pressure fluid transfer systems in performance automotive, hydraulic, and fuel line applications. This adapter bridges 6 AN male ports to 3/8 inch compression tube connections, making it essential for custom fuel systems, brake lines, and coolant circuits where reliable, leak-free connections are non-negotiable. Whether you're building a custom engine bay or repairing OEM fuel delivery infrastructure, this adapter provides the standardized interface professionals depend on.

Constructed from aluminum and finished in clear anodized coating, the 6AN Male to 3/8in Tube Adapter delivers corrosion resistance and durability in demanding under-hood environments. The clear anodized surface protects against oxidation while maintaining visibility of the adapter body for inspection and maintenance. The straight configuration eliminates flow restrictions and simplifies installation in tight engine compartments, while the 3100 series design ensures compatibility with standard automotive and industrial fittings. Weighing just 0.075 lbs and measuring 2.85 x 1.1 x 3.8 inches, this compact adapter integrates seamlessly without adding bulk to fuel or hydraulic systems.

Technicians, fabricators, and performance enthusiasts rely on this adapter when converting between AN and compression tube standards—a common requirement during engine swaps, fuel system upgrades, or restoration work. Installation is straightforward: the 6 AN male end threads directly into female AN ports, while the 3/8 inch compression fitting securely clamps onto standard tubing via a ferrule and nut. Always verify line pressure ratings and fluid compatibility before installation, and apply appropriate thread sealant to AN connections for maximum integrity in high-vibration or high-pressure applications.
