8AN Male to 1/2in Hose Barb Straight Black

The 8AN Male to 1/2in Hose Barb Straight Black fitting from Redhorse Performance is a critical component for custom fuel, coolant, and hydraulic fluid transfer systems in high-performance vehicles. This straight adapter bridges AN fittings to rubber barbed hose connections, making it essential for engine bay modifications where space is tight or routing demands a direct approach. Whether you're building a custom fuel system, upgrading coolant lines on a modified engine, or installing aftermarket hydraulic clutch systems, this adapter provides a reliable junction point between rigid AN plumbing and flexible hose runs.

Constructed from anodized aluminum with a black finish, the 8AN Male to 1/2in Hose Barb Straight Black fitting resists corrosion and integrates seamlessly into modern engine bay environments. The 8AN male port (standardized automotive AN sizing) accepts industry-standard fittings and hoses rated for high-pressure fluid transfer, while the 1/2-inch barbed outlet ensures secure hose crimping without additional clamps—though dual clamps are recommended for critical fuel and coolant applications. The straight configuration eliminates directional stress and simplifies installation in tight engine compartments where angled fittings won't fit, maintaining optimal fluid flow without turbulence or pressure loss.

This fitting benefits engine builders, performance tuners, and DIY enthusiasts upgrading fuel delivery systems, boost cooling loops, and transmission cooler circuits on turbocharged, supercharged, and naturally aspirated builds. It pairs with 1/2-inch hose (SAE J30R7, SAE J30R9, or equivalent racing-grade rubber) and accepts any 8AN male component—fuel rails, pressure regulators, filters, and distribution blocks. Installation requires only AN wrench fitment on the male side; secure the hose with worm-gear or crimp clamps rated for your system pressure to ensure long-term reliability under engine heat and vibration.
