Parker Fluid Systems Connector Division announced yesterday (February 19, 2013) that it will be replacing its line of PrestoWeld fittings (PW) with their recently released Prestolok All Metal (PLM) push-to-connect fittings by May 31, 2013.

Parker Prestolok PLM line is a high-temperature, silicone-free, all metal, push-to-connect fitting series. Parker Prestolok PLM offers more configurations than PrestoWeld, and performs well in welding applications. A complete Prestolok PLM metric range is available, which is commonly seen on robotic welding equipment.
