Usually ships in 3-8 business days.

This 1/2 in CTS AquaLock plastic straight valve works with copper, CPVC, PEX and CTS rated pipe. It is easy-to-install, no tools or tube inserts are required. The fitting can be used for hot and cold water applications. The unique O-ring guide feature provides a zero-leak connection. Unlike barb fittings, this fitting joins the tubing on-the outside, increasing the flow capacity. After a connection has been made even under maximum pressure, the tubing is able to swivel, making the fitting ideal for vibrating and dynamic applications.
