The GRACO 501684 is a check valve designed for use in piston meter kits for piston fluid flow meters. It is constructed from stainless steel and PTFE materials, making it compatible with a wide range of finishing materials, including catalysts and waterborne fluids. Its primary function is to prevent fluid leakage and backflow within GRACO equipment.

Key Features:

• Check Valve
