4AN 120 Degree PTFE Reusable Hose End Black

The 4AN 120 Degree PTFE Reusable Hose End Black from REDHORSE PERFORMANCE is a precision-engineered fitting designed for serious fuel system, coolant, and brake line applications in modified and racing vehicles. Built for mechanics and enthusiasts who demand reliability under extreme conditions, this reusable hose end eliminates the need for disposable crimp fittings and delivers a professional, leak-free connection every time. Whether you're building a high-performance engine bay or upgrading fuel delivery on a turbocharged platform, this fitting provides the durability and ease of installation that separates quality builds from corner-cut jobs.

Featuring a 120-degree bend geometry and PTFE (polytetrafluoroethylene) inner core, the 4AN fitting accommodates tight engine bay routing while maintaining superior flow characteristics and thermal stability. The reusable design allows multiple disconnect-and-reconnect cycles without degradation, making it ideal for platforms requiring frequent maintenance or seasonal updates. The black anodized aluminum construction resists corrosion and integrates seamlessly into modern engine builds, while the 4AN port size (1/4-inch nominal) handles fuel delivery, coolant circulation, and hydraulic pressure applications commonly found in EFI conversions, custom cooling loops, and suspension upgrades.

This hose end is essential for builders working with aftermarket fuel systems, custom radiator setups, and modular engine swaps where factory hard lines don't fit modern layouts. The 120-degree angle eliminates awkward bends in hose routing, reducing stress concentration points and improving system longevity. Compatible with standard 4AN hose assemblies and -4 hose sizes, it installs quickly with hand tools and requires no specialized crimping equipment—saving time on the lift and reducing failure points that plague amateur installations. Mechanics and DIY builders consistently choose REDHORSE PERFORMANCE fittings for their precision tolerances and proven track record in high-heat, high-pressure environments.
