System XFR from Ipex is now available in 14, 16 and 18-inch diameters. It is rated for high buildings and air plenums where tighter flame spread and smoke development requirements in building codes have limited the use of thermoplastic piping. The XFR joins other DWV products by Ipex including System 15, Drain-Guard double containment, and MJ Grey mechanical couplings.
