Inline Shut Off Valve 6AN Female Inlet/Outlet

The REDHORSE PERFORMANCE Inline Shut Off Valve 6AN Female Inlet/Outlet is a precision-engineered manual fuel control valve designed for high-performance fuel systems in race cars, custom builds, and performance vehicles. This valve allows operators to safely isolate fuel flow at a specific point in the line—essential for maintenance, storage, or emergency shutdown scenarios. Built for demanding applications where reliability and leak-free operation are non-negotiable, this 6AN shut-off valve serves both amateur and professional tuners who demand OEM-quality components in their custom fuel systems.

Constructed from lightweight aluminum and finished in protective black anodize, this inline shut-off valve features female AN inlet and outlet ports, making it compatible with standard 6AN fuel line fittings and adapters. The manual ball valve design enables quick, intuitive operation—simply rotate the lever 90 degrees perpendicular to the line to cut fuel flow instantly. Black anodized aluminum resists corrosion and oxidation while maintaining the sleek, professional appearance demanded in modern engine bays. At just 0.215 lbs and measuring 2.8 x 1.4 x 3.75 inches, the compact footprint allows flexible installation in tight engine compartments without requiring extensive rerouting of fuel system plumbing.

Technicians and builders favor this shut-off valve for fuel-injected performance engines, turbo systems, and nitrous oxide setups where controlled fuel supply is critical. Installation between the fuel pump and fuel rail, or anywhere along the feed line, provides a convenient manual isolation point. The 6AN female configuration accepts standard braided stainless steel fuel lines and existing AN fittings, eliminating the need for additional adapters or modifications. For anyone building or maintaining a high-performance fuel system, this REDHORSE valve delivers reliability, durability, and the precise control that separates professional-grade systems from amateur builds.
