Check Valve

Check Valve
OEM part for: Porter Cable, DeVilbiss, Black and Decker, DeWALT, Craftsman
Part Number: A19712

Product Description
This check valve is used to direct air from the cylinder to the tank, and to prevent air from going back into the pump. It is a genuine OEM part used on air compressors. It features threaded fittings to attach it to the tank, pump, and pressure switch. A faulty check valve can cause the pump to restart even with a full tank, that in turn can overload the motor. This brass part is sold individually, and the tubes are sold separately. Always make sure to drain the tank before beginning the repair.

This item works with the following types of products:
