6AN PTFE Hose Ends- N/A

The 6AN PTFE Hose Ends from REDHORSE PERFORMANCE represent the foundation of any serious fuel or coolant system upgrade for automotive enthusiasts and mechanics tackling custom fuel injection tuning, high-flow cooling conversions, or performance fuel system retrofits. These compression ferrule hose ends are engineered for reliability in demanding engine bay environments where stock rubber hose connections can't handle elevated pressures, temperature cycling, or aggressive fuel system modifications. The set of six brass ferrules ensures you have enough fittings for multi-point fuel line runs, radiator bypass loops, or future system expansion without reordering.

The 6AN PTFE Hose Ends feature a compression ferrule design that clamps securely onto PTFE (polytetrafluoroethylene) hose, creating a sealed connection that resists vibration-induced loosening and fuel weeping common in fabricated systems. Brass construction provides superior corrosion resistance compared to steel, essential for fuel contact and long-term durability in salt-prone climates or where hose sits against dissimilar metals. The natural finish protects the ferrule from oxidation while maintaining a clean, professional appearance in visible engine compartments. This compression method requires no special tools beyond a standard wrench, making installation straightforward during fuel line assembly or system modifications without requiring crimping equipment or professional fabrication services.

Mechanics and fabricators benefit most from these fittings when building custom fuel injection harnesses, upgrading carbureted vehicles to EFI, or creating multi-feed fuel systems for turbo or supercharged builds. The 6AN size (3/8-inch nominal hose ID) bridges the gap between high-flow fuel pump output and EFI injector rail inlet size, making it ideal for single or dual-feed configurations on mid-range displacement engines. These hose ends are compatible with any aftermarket fuel rail, surge tank, or fuel block featuring 6AN ORB (O-ring boss) ports, and work seamlessly with braided stainless steel or PTFE hose to create leak-free fuel systems rated for forced induction applications and fuel pressures exceeding 60 PSI.
