6AN Male to 11/16-18 Inverted Flare Male CLR

The 6AN Male to 11/16-18 Inverted Flare Male CLR adapter from REDHORSE PERFORMANCE is a precision hydraulic and fuel system connector designed for high-performance automotive applications. This adapter is essential for custom fuel system builds, turbo installations, and performance engine swaps where OEM fuel line routing may not accommodate upgraded components. It is ideal for professional mechanics and serious automotive enthusiasts seeking reliability under pressure.

Constructed with precision machining, this male-to-male adapter features an inverted flare design on the 11/16-18 side, which creates a stronger, more reliable seal under vibration and thermal cycling than conventional flared fittings. The 6AN (AN6) inlet accepts industry-standard -6 hose with appropriate fittings, while the 11/16-18 outlet threads onto components using SAE inverted flare specifications. The lightweight construction and chromium-plated finish resist corrosion from fuel vapors, coolant exposure, and road salt.

This adapter is particularly beneficial for those integrating aftermarket fuel pumps or rerouting brake fluid in modified vehicles. Its compact design allows for seamless integration into tight engine bays, making it a versatile choice for various applications. Whether you're working on a custom engine build or upgrading your vehicle's fuel system, this fitting delivers the cross-compatibility you need.
