The 6AN Male to 10AN O-ring Port Adapter Clear by REDHORSE PERFORMANCE is an essential hydraulic line transition fitting for custom fuel, coolant, and brake system builds where port sizes don't match directly. Whether you're fabricating a modified fuel rail, upgrading to larger-diameter feed lines, or integrating aftermarket cooling components, this adapter bridges the gap between 6AN and 10AN ports without requiring complete line replacements. Designed for high-performance and street-rod applications, it allows builders to mix component sizes when stock or OEM configurations aren't compatible with custom platform swaps or engine conversions.
This adapter features a 6AN male thread on one end and a 10AN O-ring port (ORB) on the other, eliminating the need for separate hose sections and reducing potential leak points. The clear anodized finish provides corrosion resistance and visibility for fluid inspection while maintaining structural integrity under pressure cycling common in performance fuel and cooling circuits. O-ring port design creates a metal-to-metal seal that is more reliable than NPT (National Pipe Thread) connections in high-vibration environments typical of turbocharged and supercharged platforms. The compact 2.84-inch length allows installation in tight engine bay spaces without requiring extensive bracket modifications or rework.
Professional mechanics, engine builders, and suspension tuners rely on REDHORSE adapters when downsizing or upsizing fuel system architectures during LS swaps, turbo retrofits, or complete fuel cell installations. Compatibility spans aluminum and steel block engines where fuel pump outlet specs differ from fuel rail inlet requirements, or when upgrading cooling capacity on modular platforms. Installation requires standard -6 and -10 hose fittings and a thread-locking compound rated for fuel exposure; always verify system pressure ratings match adapter specifications to avoid component failure under boost or high-demand circuit conditions.
