NVent LLC, a joint enterprise recently formed by Nibco Inc. and Victaulic, will show its new product PermaLynx - a permanent push-to-connect copper pipe joining system. The PermaLynx system offers a complete line of fittings and valves for joining 1/2- to 2-inch K, L, and M copper tube. PermaLynx installs more than twice as fast as sweat solder systems, which results in significant labor savings, says the company.
