Low Pressure Flapper Valve, Male AN Fittings

These high-quality check valves have a low-tension spring to allow virtually unimpeded flow in one direction, yet the O-ring sealed internal flapper positively prevents flow in the opposite direction. They are used in fuel systems, oil scavenge lines, and other low pressure applications where a check valve is required. Nominal 0.5 psi cracking pressure. Aluminum body with male AN/JIC fittings.
