4AN Male to 4AN Male Tee Blue

The 4AN Male to 4AN Male Tee Blue from REDHORSE PERFORMANCE is a precision aluminum adapter fitting designed for high-pressure hydraulic and fuel system applications. This tee connector splits a single 4 AN (AN4) male inlet into two 4 AN male outlets, making it essential for custom fuel lines, transmission cooler setups, brake systems, and other performance fluid distribution networks. Built for racing, street performance, and industrial hydraulic applications where reliability and leak-free connections are non-negotiable.

Constructed from lightweight aluminum and finished in blue anodized coating, this fitting combines corrosion resistance with minimal weight gain—critical for performance builds where every fraction of a pound matters. The anodized surface protects against oxidation and fluid degradation while the precision-machined male threads ensure thread-locking compatibility with standard 4 AN hoses and fittings. REDHORSE Performance fittings are engineered to strict tolerances and rated for demanding pressure environments, delivering consistent sealing and durability across thermal cycles and vibration exposure common in high-performance automotive and industrial systems.

This adapter is ideal for enthusiasts building custom fuel distribution systems, upgrading cooling circuits, or designing multi-outlet brake or transmission lines. The compact 2.9 x 1.1 x 3.85-inch footprint allows flexible routing in tight engine bays while maintaining structural integrity. Installation is straightforward—simply thread the inlet line to the single 4 AN male port and connect your two destination lines to the outlet ports using standard 4 AN hose ends and PTFE tape or thread sealant for optimal leak prevention. Compatible with any system using 4 AN (AN4) metric fittings and tubing.
