Inline Shut Off Valve 6AN Male Inlet/Outlet

The Inline Shut Off Valve 6AN Male Inlet/Outlet by Redhorse Performance is a critical flow control component for high-performance fuel, coolant, and fluid systems in modified vehicles. Whether you're building a turbo setup, custom cooling loop, or fuel system upgrade, this shut-off valve lets you isolate sections of your circuit for maintenance, testing, or emergency fuel cutoff without breaking fittings or draining the entire system. It's essential for serious engine builders and enthusiasts who demand precision control over pressurized fluid pathways.

This valve features 6AN male threaded ports on both inlet and outlet, ensuring seamless integration into standard -6 hose and fitting ecosystems used throughout modern performance platforms. The compact 3.65 × 1.4 × 3.8 inch footprint and light 0.2 lb weight make it easy to tuck into tight engine bays without adding bulk or complexity. The ball-valve design provides positive on/off control with minimal restriction when fully open, preserving system pressure and flow rates critical to turbochargers, fuel injection, and cooling circuits. Redhorse Performance's engineering ensures consistent, reliable operation across repeated cycles and high-pressure cycles typical in forced-induction and modified cooling applications.

Builders and tuners choose this inline shut-off valve for fuel system isolation during dyno runs, coolant system troubleshooting, or emergency fuel shutdowns on street and track vehicles. Its 6AN male configuration pairs directly with standard -6 braided hose, fittings, and adapters used in LS engine swaps, turbo builds, and custom cooling setups on domestic and import platforms. Installation is straightforward—simply plumb it into your circuit between the supply line and destination component, ensuring the handle aligns with flow direction. This valve is indispensable for any serious performance build where system flexibility and rapid circuit isolation are non-negotiable.
