4AN PTFE Hose End Replacement RHP Ferrules

The 4AN PTFE Hose End Replacement RHP Ferrules by REDHORSE PERFORMANCE are essential components for custom fuel, coolant, and hydraulic line assemblies in high-performance automotive applications. These ferrules are designed for builders and mechanics who require reliable connections in modified engine bays where standard hose routing is insufficient for custom plumbing layouts.

Engineered with PTFE (polytetrafluoroethylene) sealing surfaces, these ferrules resist thermal degradation and maintain compression integrity across a wide temperature range, making them suitable for both fuel injection systems and forced-induction applications. The innovative design creates a metal-to-metal wedge seat that securely grips the hose without crushing the reinforced synthetic material, effectively preventing leaks under vibration.

Ideal for mechanics and engine builders working on fuel systems, coolant circuits, and hydraulic lines, these ferrules ensure leak-free connections even in tight engine compartments. With a compact design and lightweight construction, they are perfect for weight-conscious builds while maintaining structural integrity during engine operation.
