Fabricated Check Valve 16AN Male Outlets

The Fabricated Check Valve 16AN Male Outlets by PWR NORTH AMERICA is an essential fluid-management component for custom fuel, oil, and cooling system builds in high-performance automotive applications. Check valves serve a critical function: they allow fluid flow in one direction while preventing backflow, which protects fuel pumps, oil circuits, and radiator systems from pressure spikes and siphoning during engine shutdown or deceleration events. Whether you're building a carbureted street engine, a turbocharged fuel system, or a custom cooling loop, a quality check valve prevents cavitation damage and ensures system integrity under demanding conditions.

This fabricated design features dual 16AN male outlets, making it compatible with industry-standard -16 AN hose fittings and adapters commonly used in professional race and street-performance fuel delivery systems. The 16AN size handles high-volume fuel transfer rates typical of supercharged or naturally aspirated engines operating at elevated boost or RPM levels, while the dual-outlet configuration allows flexible installation in series or parallel arrangements within your system layout. PWR NORTH AMERICA's fabricated construction ensures precise internal cracking pressure and reliable one-way flow control, eliminating costly fuel leaks or system pressure loss that can compromise carburetor tuning or fuel injection stability.

Ideal for restomods, drag racing builds, and street machines running mechanical fuel pumps or aftermarket electric fuel systems, this check valve integrates seamlessly into custom fuel rails, return lines, and pressurized cooling circuits. The compact 4.8 × 3.1 × 9-inch footprint allows installation in tight engine bays, while the lightweight 0.41-pound construction adds minimal system weight. Installers appreciate the straightforward dual-port design for rapid hose routing decisions, and the robust fabricated valve body resists vibration-induced failure common in high-performance environments—making it an indispensable safeguard for engines where fuel system reliability directly impacts both performance and safety.
