Speedaire 6X210 In-Tank Check Valve 1 Inch Outlet

Speedaire 6X210 In-Tank Check Valve is a brass-bodied, in-tank one-way valve for air compressors. It has a 1" female pipe thread (FPT) inlet and a 1" male pipe thread (MPT) outlet, and is rated for a maximum operating pressure of 450 psi. Mounted in the line between the compressor pump discharge and the receiver tank, it prevents backflow from the tank into the pump when the unit shuts off, helping retain tank pressure and protecting the pump from backflow-related wear. Brass construction resists corrosion in typical workshop environments, and the compact inline form supports straightforward installation in 1" porting on both sides. This configuration is compatible with Speedaire systems and other reciprocating compressors that use 1" connections, making it a practical replacement part for maintaining reliable compressor operation.
