Inline Shut Off Valve 10AN Female Inlet/Outlet

The Inline Shut Off Valve 10AN Female Inlet/Outlet by Redhorse Performance is a precision fluid management component engineered for serious engine builders, fuel system tuners, and performance automotive enthusiasts. This compact valve sits inline within your fuel, coolant, or hydraulic lines, allowing you to isolate flow with a simple quarter-turn mechanism—essential when debugging fuel pressure issues, swapping components, or performing maintenance without draining entire systems. Whether you're running a forced induction setup, a complex fuel injection platform, or managing coolant flow in a high-horsepower build, this valve provides the control and reliability that separates professional installations from amateur work.

Constructed with 10AN female inlet and outlet ports, this valve integrates seamlessly into braided stainless steel or rubber hose assemblies using standard AN fittings—no adapters or reducers required. The compact 3.9 x 1.55 x 5.3 inch footprint and lightweight 0.45 lb design make it easy to mount in tight engine bays without sacrificing durability or flow capacity. The ball-valve design ensures zero leakage when closed and unrestricted flow when open, critical for maintaining fuel pressure stability and preventing vapor lock in high-heat environments. Redhorse Performance's manufacturing standards ensure consistent tolerances and longevity across repeated cycle testing, so you can trust this valve through thousands of track hours or daily driving demands.

Mechanics and tuners favor this inline shut-off valve for fuel system diagnostics, turbo upgrades, and custom coolant routing on LS swaps, supercharged builds, and motorsport applications. Installation is straightforward—simply cut your line at the desired isolation point, connect both ends via the 10AN female ports, and secure the valve with a zip tie or P-clamp to prevent vibration-induced loosening. Its universal 10AN compatibility means it works with any manufacturer's hose or braided line fitting on the market, making it an indispensable troubleshooting tool for any serious garage.
