10an 90-Deg Hose End

The 10AN 90-degree hose end from SETRAB Oil Coolers is a precision fluid-line fitting engineered for high-performance engine cooling and lubrication systems. Whether you're building a custom cooling circuit for a turbocharged engine, upgrading an oil cooler setup, or fabricating a race-spec fuel or fluid line, this 90-degree adapter provides the directional flexibility needed to route hoses cleanly through tight engine bays and around complex component layouts. For mechanics, fabricators, and performance enthusiasts, directional hose ends are essential to avoiding sharp bends, reducing pressure loss, and maintaining system integrity under demanding conditions.

This fitting is manufactured in aluminum construction with gray and black anodized finishes, offering corrosion resistance and a professional appearance in engine bays. The 10 AN designation (AN10) refers to the AN (Army-Navy) hose standard, with 10 indicating a nominal inside diameter of 5/8 inch—a common size for oil cooler lines, transmission coolers, and fuel systems in performance applications. The 90-degree configuration allows hose to exit perpendicular to the port, eliminating the need for multiple fittings and reducing turbulence at connection points. Both the inlet and outlet are 10 AN female threads, making this a direct port-to-hose adapter that integrates seamlessly into existing cooling circuits without additional reducer fittings or adapters.

This hose end is ideal for street performance builds, race-spec cooling systems, and any application where space constraints demand compact, efficient fluid routing. It pairs directly with braided AN10 hose and standard AN female-threaded component ports found on SETRAB oil coolers, transmission coolers, fuel pressure regulators, and aftermarket thermostats. Weighing just 0.25 lbs, it adds negligible mass while enabling cleaner engine bay layouts. Installation is straightforward: simply connect braided hose to the fitting using AN hose clamps or compression fittings. Always verify hose ID matches the AN rating and torque all threaded connections to manufacturer specifications to ensure leak-free operation under full system pressure.
