The future is here with Viega PureFlow Press. As the leader in press technology, Viega was the first to offer a true press system to the PEX market. Available in sizes from 3/8 in. to 2 in., the bronze PureFlow transition coupling simplifies plumbing projects by securely connecting PureFlow and ProPress fittings with a durable EPDM seal. The PureFlow press system installs in just four easy steps: cut the tube to length, remove any burrs and surface imperfections, measure and mark the fitting insertion depth, and use a press tool for a secure connection. Smart Connect technology identifies unpressed connections during pressure testing to ensure proper connections the first time and eliminate callbacks. Approved to the most codes and standards of any other press fitting system (IPC, UPC and NSF included), and with more than 400 different fitting configurations to suit virtually any type of plumbing or HVAC job, Viega press fittings are the top choice of professionals around the globe.
