4AN to 4AN Blue Male Female

The REDHORSE PERFORMANCE 4AN to 4AN Blue Male Female adapter is a precision hydraulic fitting designed for high-performance fluid transfer systems in motorsports, industrial, and tactical applications. This male-to-female AN coupling enables seamless connection between compatible hose assemblies and component ports, eliminating the need for separate adapter pieces and reducing potential leak points. Built to meet the demanding requirements of custom fuel systems, cooling circuits, and pressurized fluid lines, this fitting serves enthusiasts and professionals who prioritize reliability and leak-free performance.

The 4AN designation indicates a nominal bore diameter optimized for moderate to high flow applications while maintaining a compact footprint. REDHORSE PERFORMANCE fittings are manufactured from aircraft-grade aluminum alloy with hard-anodized finishes that resist corrosion and fluid degradation, ensuring durability in harsh environments. The blue anodizing provides both aesthetic appeal and functional identification within color-coded fluid systems, making circuit management straightforward during assembly and maintenance. The male-female configuration allows for direct mating of complementary hose ends, delivering secure, bubble-tight connections under pressure without additional components.

This adapter is ideal for builders and technicians working on drag racing fuel systems, custom cooling loops, hydraulic brake circuits, and pressure-fed applications where thread count and fitting integrity are non-negotiable. Installation requires only standard wrenches or fitting tools; the compact 2.75 x 1.1 x 3.8-inch dimensions fit easily into confined engine bays and component housings. Compatibility with all standard 4AN hose sizes and AN-threaded ports ensures universal integration across diverse platforms. For demanding applications requiring repeated assembly and disassembly, the robust aluminum construction and precision machining of the REDHORSE PERFORMANCE 4AN to 4AN Blue Male Female fitting deliver performance and longevity season after season.
