8AN Bulkhead Adapter Blue Male Male

The 8AN Bulkhead Adapter Blue Male Male from REDHORSE PERFORMANCE is a precision hydraulic fitting designed for custom fuel, coolant, and brake line routing in high-performance vehicle builds. Bulkhead adapters are essential when you need to pass AN hose or hard lines through firewall, chassis, or engine bay barriers while maintaining a sealed, leak-free connection. Whether you're fabricating a custom fuel system, upgrading a race car's cooling circuit, or building a show-quality engine bay, this male-to-male adapter enables clean transitions without compromised flow or safety.

This 8AN adapter features dual male AN ports, allowing you to join two female-threaded system components or hose ends on either side of a partition. The blue anodized aluminum construction provides corrosion resistance and aesthetic consistency with modern engine dress-up standards while maintaining structural integrity under pressure cycling. The 37-degree JIC flare angle (AN standard) ensures reliable sealing across repeated assembly and disassembly cycles, critical for DIY tuning or professional service scenarios. Compact dimensions of 2.8 x 1.4 x 3.8 inches allow installation in tight engine compartments, and the 0.11 lbs weight has zero impact on vehicle dynamics or fuel system resonance.

Mechanics and fabricators building custom fuel injection, turbo coolant loops, remote oil filtration, or competition brake systems rely on REDHORSE PERFORMANCE fittings for reliability under extreme conditions. The 8AN size suits LS, small-block Chevy, and forced-induction platforms where flow demand justifies larger hose diameter. Installation requires only standard AN wrenches and thread-sealing compound (PTFE tape not recommended for JIC flares); ensure both mating surfaces are clean and undamaged before assembly. This adapter pairs seamlessly with 8AN hose, hard line, and pump/filter port combinations across street, strip, and circuit applications.
