The DeVilbiss DAC-252 Check Valve is an inline air-line component that prevents backflow in compressed-air systems. It features a 5/8" compression connection on one end and a 1/2" male pipe thread (MPT) on the other, enabling secure coupling between hoses or tools in DeVilbiss, Porter-Cable, and Craftsman setups. Designed to maintain pressure and protect equipment by stopping reverse airflow, it is suitable for use in spray equipment and general air-tool lines where backflow prevention is required.
