Easy Pro 3/8 - 1/2 inch Barbed Inlet Air Check Valve - 3/4 inch MPT
3/8″–1/2″ Barbed Inlet Air Check Valve with 3/4″ MPT
This air check valve features a stepped barbed inlet that fits 3/8″ (0.43″ / 11 mm) and 1/2″ (0.55″ / 14 mm) tubing, paired with a 3/4″ male pipe thread (MPT) outlet. Air is designed to flow from the barbed side toward the threaded end, preventing water from backing up into the air compressor.
