6AN Male to M16x1.5 Female Blue

The 6AN Male to M16x1.5 Female Blue adapter from REDHORSE PERFORMANCE is a precision hose fitting engineered for high-performance fuel system, coolant line, and hydraulic applications in modified vehicles. Designed for mechanics and enthusiasts who demand reliability in custom plumbing configurations, this adapter bridges incompatible thread standards without compromise. Whether you're building a custom fuel injection system, upgrading cooling circuits, or fabricating brake hydraulics on a race car or street machine, this fitting ensures leak-free connections under pressure.

Constructed with precision-machined aluminum and finished in vibrant blue for easy identification in complex engine bays, the 6AN Male to M16x1.5 Female Blue features a 6AN male port that accepts standard -6 braided hose and an M16x1.5 female metric port for direct integration with OEM or aftermarket components. The M16x1.5 thread pitch is the ISO standard metric equivalent to many European performance parts and some domestic turbo applications. Hard-anodized construction resists corrosion and fuel degradation, while the compact 2.8 x 1.15 x 3.8 inch footprint allows installation in tight engine compartment spaces. At just 0.06 lbs, this adapter adds negligible weight to your fuel or cooling system.

This adapter is essential for builders integrating aftermarket fuel pumps, intercooler systems, or auxiliary cooling loops into vehicles with mixed fastener standards. It's particularly valuable when sourcing metric-threaded components from European manufacturers or adapting universal -6 AN hose systems to factory metric ports. Installation requires only a wrench and proper hose-sealing compound on NPT threads if applicable; ensure all connections are torqued to spec to prevent leaks under boost or high-flow conditions. Compatible with gasoline, diesel, and most synthetic coolants, this REDHORSE fitting delivers the durability serious tuners expect in daily-driven performance vehicles.
