4AN 45 Degree PTFE Reusable Hose End Black

The 4AN 45 Degree PTFE Reusable Hose End Black from REDHORSE PERFORMANCE is a precision-engineered fitting designed for custom fuel, oil, and coolant line applications in modified vehicles and high-performance engine builds. This hose end serves as the critical connection point between braided stainless steel hose and your engine bay plumbing, allowing you to route lines around tight engine compartments without kinking or restricting flow.

The 45-degree angle design allows flexible routing in cramped engine bays while maintaining optimal flow dynamics and reducing stress on hose connections under pressure and vibration. PTFE (polytetrafluoroethylene) sealing material provides superior chemical resistance to modern fuels, synthetic oils, and aggressive coolants without degradation, ensuring leak-free performance across a wide temperature range. The black anodized aluminum body resists corrosion from road salt and engine bay humidity, while the reusable design lets you assemble or disassemble lines multiple times without replacing the fitting itself.

Mechanics and fabricators favor REDHORSE fittings for custom fuel injection retrofits, forced induction builds, and other high-performance applications. This fitting is particularly beneficial for those upgrading to a turbo system, installing a remote oil cooler, or running a custom fuel system on their street rod or race car. With its reliable performance and ease of use, the 4AN 45 Degree PTFE Reusable Hose End is an essential component for any serious automotive enthusiast.
