The Victaulic high-density polyethylene (HDPE) pipe-joining system provides a full line of Installation-Ready™ and grooved solutions from 2” to 36”. The Style 905 Refuse-to-Fuse™ HDPE coupling joins plain-end HDPE pipe 2-8” in diameter. The installation-ready coupling contains stainless-steel restraint rings that bite into the outside diameter as the coupling housing segments are tightened. With no need for disassembly, the assembly process is quick and requires no loose parts. The coupling is also visually inspectable, allowing installers to see a bolt-pad-to-bolt-pad confirmation that the joint is properly assembled.
