Union AN Male -6

The Union AN Male -6 is a straight adapter fitting designed to connect two 6 AN male ports in fluid systems requiring reliable, leak-free hydraulic or fuel line integration. This fitting is essential for custom hydraulic builds, fuel system modifications, and high-pressure applications where secure AN port connections are non-negotiable. Whether you're assembling a performance fuel system, brake line configuration, or coolant loop, this adapter bridges two matching male threads to create a continuous, pressurized circuit without flow interruption.

Constructed from aluminum and finished in black anodized coating, the Union AN Male -6 delivers durability and corrosion resistance in demanding underhood and pressurized environments. The anodized surface protects against oxidation and galvanic corrosion while maintaining a professional appearance across engine bays and chassis installations. The straight-through design minimizes turbulence and pressure drop, ensuring optimal flow dynamics in fuel, coolant, or hydraulic systems. AN-6 ports are industry-standard on professional racing fuel systems, aftermarket fuel rails, and custom hydraulic manifolds, making this adapter a critical interchange component for precision plumbing work.

Professional mechanics, fabricators, and automotive enthusiasts rely on AN adapters to eliminate mismatched port configurations and simplify complex fuel or hydraulic layouts. Installation is straightforward—thread both male AN-6 connections into the adapter with appropriate sealant or PTFE tape to ensure a hermetic seal under operating pressure. This fitting is ideal for upgrading fuel systems on turbocharged engines, refurbishing vintage race cars, or standardizing custom hydraulic circuits where AN-6 compatibility is required throughout the network.
