Watts Aqualock 1/2 In. x 1/2 In. Push-to-Connect Plastic Coupling

These AquaLock mini couplings works with plastic or soft copper tubing. They are easy to install, no tools or tube inserts are required. These fittings can be used for hot and cold water applications. Their unique O-rings guide feature provides a zero-leak connection. Unlike barb fittings, these fittings join 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.
