6AN 120 Degree PTFE Reusable Hose End Clear

The 6AN 120 Degree PTFE Reusable Hose End Clear from REDHORSE PERFORMANCE is a precision-engineered fitting designed for high-performance fuel, coolant, and brake line applications in custom automotive builds. Built for enthusiasts and professional mechanics who demand reliability in modified fuel systems, turbo kits, and custom cooling loops, this swivel hose end accommodates tight engine bay layouts where standard 90-degree fittings won't fit. Its reusable design eliminates the need for single-use crimp fittings, saving money across multiple projects while maintaining critical seal integrity under pressure.

The 120-degree angle geometry addresses real-world plumbing challenges in custom engine bays, offering superior fitment compared to standard 90 or 45-degree alternatives. Constructed from aluminum with a clear anodized finish, the fitting resists corrosion while allowing visual inspection of PTFE line condition through the transparent body. The swivel design permits 360-degree rotation at the hose attachment point, reducing installation stress and preventing line twist during system pressurization—a critical feature when working with -6AN braided hose in confined spaces. The 6AN bore (compatible with -6AN hose and fittings) delivers proven performance in fuel injection systems, EFI conversions, and auxiliary cooling circuits without flow restriction.

This fitting excels in street rod builds, LS engine swaps, EFI fuel rail installations, and custom water cooling systems where space constraints demand non-standard routing. The reusable construction makes it ideal for prototype development and frequent system modifications—common in racing and turbo builds where hose geometry changes between iterations. Installation requires matching -6AN female fittings on both the component and line side; verify your existing fuel rail, water pump inlet, or fuel pressure regulator accepts 6AN threads before ordering. Combine with PTFE-lined braided hose, quality AN hose clamps, and proper thread sealant for a lasting, leak-free system that handles fuel injection pressures and coolant flow with confidence.
