Fitting 3/8inTube to -6AN

The Fitting 3/8in Tube to -6AN by DERALE is a precision adapter fitting engineered for fluid system integration in high-performance cooling, fuel, and hydraulic applications. This straight compression fitting bridges two industry-standard connection types—3/8 inch compression tubing and -6 AN (JIC flare) ports—eliminating the need for custom solutions or multiple adapters. Built for professionals who demand reliable, leak-free connections, this fitting serves custom cooling systems, fuel injection setups, and transmission cooler installations where space is tight and compatibility demands are specific.

Constructed from aluminum and finished in black anodize, the fitting resists corrosion while maintaining a low-profile footprint at just 2.75 inches in length. The straight configuration ensures direct flow paths without flow restriction or turbulence, critical for systems where pressure consistency and thermal stability matter. Black anodized aluminum provides both durability and aesthetic integration into custom builds, while the -6AN male thread end accepts standard AN fittings and hoses rated for automotive and motorsport duty. The 3/8 inch compression end securely clamps onto standard tubing without requiring flaring or specialized tools, simplifying installation and reducing assembly time.

This adapter is ideal for fabricators, engine builders, and technicians customizing cooling or fuel systems on street rods, race vehicles, and modified engines. It accommodates both OEM-style compression tubing runs and aftermarket AN-style hard lines, making it invaluable for transitioning between system sections or integrating third-party coolers and components. Installation requires no special equipment—compress fittings or hand-tighten AN connections per system specifications. Verify line compatibility and pressure ratings before assembly to ensure the fitting matches your system's maximum operating pressure and fluid type.
