6AN Crimp Style Hose End Black 45

The 6AN Crimp Style Hose End Black 45 from REDHORSE PERFORMANCE is a precision-engineered hydraulic fitting designed for high-performance fuel, oil, and coolant line applications in modified vehicles. Built for serious automotive enthusiasts and professional mechanics, this 45-degree angled hose end delivers secure, leak-free connections in tight engine compartments where straight fittings won't fit. Whether you're upgrading a fuel system on a turbocharged build, routing braided lines through a custom harness, or installing high-capacity cooling lines, this fitting provides the reliability required for engine modifications where stock hose routing simply isn't an option.

The 45-degree angle design minimizes stress on hose bends and reduces the risk of kinks that can restrict flow or fail under pressure cycling—critical when working with forced-induction systems or high-flow cooling setups. The crimp-style connection uses REDHORSE PERFORMANCE's proven swaging process that creates a permanent, hydrostatic seal stronger than the hose itself; no reusable fittings or hose clamps required. The black finish resists corrosion and blends seamlessly into modern engine bay aesthetics while the 6AN size (3/8-inch inner diameter) handles flow rates up to 60+ GPM, making it ideal for fuel delivery systems, turbo oil supply lines, coolant bypasses, and intercooler plumbing on street and race applications alike.

Professional mechanics and weekend builders rely on REDHORSE PERFORMANCE fittings for builds ranging from mild bolt-on upgrades to full engine conversions. This fitting pairs directly with 6AN braided hose and matches standard AN hose end adapters found in fuel system kits, transmission cooler setups, and custom plumbing configurations. Installation requires a hose crimper and proper assembly technique—the small form factor (measuring 2.75 x 1 x 3.8 inches) allows routing in confined spaces without sacrificing strength. Use this hose end when precision routing, reliability under pressure, and a permanent sealed connection are non-negotiable for your modification project.
