Check Valve 3540-10
This 1/2 inch CTS AquaLock™ plastic check valve works with copper, CPVC, PEX, and CTS rated pipe.
Installation is easy, as no tools or tube inserts are required.
The fitting can be used for applications involving hot and cold water.
The unique O-ring guide feature ensures a zero-leak connection.
Unlike barb fittings, this fitting joins the tubing on the outside, which increases flow capacity.
After a connection has been made, even under maximum pressure, the tubing is able to swivel, making the fitting ideal for dynamic and vibrating applications.
