Fabricated Check Valve -20AN Male Outlets

The PWR NORTH AMERICA Fabricated Check Valve -20AN Male Outlets (part number 70-11003) is a precision-engineered one-way flow control component designed for high-performance cooling and fluid systems. This check valve is essential for builders and technicians working on custom cooling systems where OEM factory parts are unavailable or incompatible with aftermarket radiators, electric fan conversions, or remote-mounted auxiliary coolers.

This aluminum check valve features a flapper design that allows fluid to flow freely in one direction while preventing backflow, a critical function in radiator circuits and auxiliary cooler installations. The valve accepts -20AN male inlets and outlets, making it compatible with standard AN-threaded hose fittings and hard-line systems common in motorsports and industrial cooling applications. The aluminum body with natural finish offers a weight advantage over steel counterparts while maintaining corrosion resistance.

This check valve is particularly valuable in hot-rod and drag racing applications, where maintaining system integrity is crucial. The compact dimensions (5.15 × 2.35 × 6.7 inches) allow for easy integration into tight engine bay layouts without excessive bulk or mounting complexity. Builders can utilize the auxiliary ports for gauge lines or bleeder valves, enhancing the versatility of their cooling systems.
