Industrial 1-1/4” FPT x 1-1/4” MPT air compressor check valve designed to prevent reverse flow in compressed-air lines. It provides a 1-1/4” female pipe thread on one end and a 1-1/4” male pipe thread on the other, enabling straightforward installation between components in pneumatic systems. This check valve helps protect compressors and downstream equipment in industrial tool circuits and line runs by allowing flow in one direction while blocking backflow.
