PEX Quick-Connect End Cap, 1/4-In.

1/4 OD End Cap Quick-Connect. Watts Item Order # 17103090. This Watts Quick-Connect fitting is easy to install. It features corrosion resistant teeth which allow the connectors to interconnect with multiple materials without the need for special tools or tube inserts. Watts Quick-Connects can be used for hot and cold water applications. The unique O-ring guide feature insures zero-leak connections. 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.
