10AN Male to 5/8in Hose Barb Straight Black

The 10AN male to 5/8in hose barb straight black adapter from REDHORSE PERFORMANCE is a critical component for custom fuel, coolant, and hydraulic line routing in engine modifications and performance builds. This fitting bridges the gap between AN-standard (Army Navy) threaded ports and barbed hose connections, making it essential for mechanics and enthusiasts upgrading fuel systems, intercooler setups, or auxiliary cooling loops on turbocharged and naturally aspirated engines.

Constructed with a straight-flow design, this adapter features a 10AN male thread on one end and a 5/8-inch barb outlet, allowing direct connection to reinforced braided hose without reducers or secondary adapters. The black finish indicates anodized or powder-coated aluminum construction, providing corrosion resistance in engine bay environments while maintaining excellent pressure ratings required for fuel injection systems and turbo circuits. The straight configuration minimizes turbulence and pressure loss—critical when moving high-flow fuel or coolant at elevated temperatures and pressures typical in modified vehicle applications.

Professional installers and DIY builders rely on REDHORSE Performance fittings for fuel system upgrades, standalone engine management installations, and custom cooling solutions on drag cars, street rods, and daily-driven performance vehicles. This adapter is compatible with standard 5/8-inch ID braided hose secured with hose clamps, and its compact 2.8 x 1.4 x 3.8-inch footprint fits tight engine bay layouts. Proper installation requires stainless steel clamps and hose-barb-compatible crimping or clamping techniques to ensure leak-free operation under sustained boost and high-flow conditions.
