Product Details


3/4" x 3/4 Inch Female NPT In Line Brass Compressed Air Check Valve CIL3434U New

Product Description

Brand new 3/4" 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 threads on both ends. This valve prevents back flow or tank pressure from getting back to 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. If your compressor does not use an unloader, this port can simply be plugged.


Valve Inlet Threads- 3/4" Female NPT (measures about 1" in diameter)
Outlet Threads- 3/4" Female NPT (measures about 1" in diameter)
Side Port- 1/8" Female NPT (measures about 10/32 in diameter)
Total Length- 3-1/4"
The Inlet side of this valve is marked "IN"

Double check that you have this valve installed in the right direction before operating.
Improper installation can cause damage to compressor pumps
