In-Line Brass Check Valve 1-1/2" Female NPT x 1-1/2" Female NPT
Brand new 1-1/2" Female NPT in-line air compressor check valve. This check valve features a 1/8" female NPT port in the side to go to an unloader valve if needed. This is a universal inline check valve with female NPT threads on each end. This valve prevents back flow or tank pressure from getting back into the air compressor pump once the compressor is shut off. The 1/8" unloader port on the side of the valve is used to relieve pressure from the pump once it has shut off.
Improper installation can cause damage to compressor pumps.
