WATTS® 17103042 Straight Valve, 3/8 in Nominal, OD Tube x MNPT End Style, Import

This 3/8 in OD x 3/8 in MNPT quick connect fitting works with copper, CPVC, LPDE, PEX, MPDE, HDPE and polybutylene tubing. It is easy to install, no tools or tube inserts are required and the fittings can be used for hot and cold water applications. The unique O-ring guide feature insures zero-leak connections. Unlike barb fittings, it 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 it ideal for vibrating and dynamic applications.
