-10AN Roll Over Valve

The -10AN Roll Over Valve is a precision internal check valve engineered for high-performance fuel and fluid systems in motorsports, aviation, and off-road applications. Designed with an internal architecture, this valve prevents backflow and protects critical engine components during inverted maneuvers, sudden deceleration, or system overpressure events. Built for professionals who demand reliability in extreme conditions, the -10AN Roll Over Valve meets the stringent requirements of race teams, vintage aircraft operators, and performance enthusiasts who cannot tolerate fuel starvation or line pressure loss.

Manufactured from aerospace-grade aluminum with black anodized finish, this valve body resists corrosion and maintains structural integrity under sustained pressure cycling. The 10 AN male outlet connection ensures compatibility with standard braided stainless or AN-rated fuel line systems, while precision-machined internal ports minimize flow restriction and pressure drop. Nylon washers seal the connection cleanly without thread sealant, reducing assembly time and ensuring repeatable torque specifications across multiple installations and maintenance cycles.

Installation suits any fuel system where gravity feed or siphoning poses a risk—gravity-fed carburetors, high-wing aircraft, or vehicles equipped with remote fuel cells mounted above engine height. The compact footprint (4.53 x 1.5 x 5.91 inches) fits tight engine bays and custom plumbing configurations. Weighing only 0.27 lbs, this valve adds negligible weight while providing critical flow protection. Each unit ships individually tested, making it suitable for single-vehicle builds or fleet maintenance programs requiring point-of-use replacement.
