10an 90-Degree Male Bulkhead adapter Black

The 10AN 90-Degree Male Bulkhead Adapter Black from REDHORSE PERFORMANCE is a critical fitting for custom fuel, oil, and coolant line routing in modified vehicles. This adapter serves as a sealed pass-through for your engine bay plumbing, allowing you to transition from internal fuel rails or oil galleries to external braided hose runs without threading directly through firewall holes. Mechanics and fabricators rely on quality bulkhead adapters when building custom fuel systems, turbo oil supply and return lines, or complex cooling circuits that demand leak-free performance under pressure.

The 10AN size delivers rated flow capacity for most high-performance fuel injection, turbo lubrication, and coolant applications up to motorsport-grade pressures. The 90-degree male configuration allows the hose fitting to exit perpendicular to the bulkhead surface, eliminating sharp bends that can kink braided lines and reducing installation footprint in tight engine bays. REDHORSE's black anodized aluminum construction resists corrosion and maintains structural integrity across thermal cycles, while the precision-machined bulkhead shoulder ensures a positive seal when paired with a compatible female adapter on the opposite side of your firewall or component wall.

This adapter is essential for turbo conversions, fuel system upgrades, and custom oil cooling setups where factory bulkhead penetrations don't align with your plumbing path. It pairs with 10AN braided hose, crimped hose ends, and female bulkhead adapters to form a complete sealed assembly. Ensure your mating adapter is also 10AN female and that the installation surface is properly sealed with thread sealant or o-ring backup to maintain system pressure integrity. Weight and compact dimensions make it ideal for tight fabrication work in street cars, track builds, and engine swap projects.
