The Style W257 dynamic movement joint from Victaulic is preassembled and reduces installation complexity to threaded rod installations of the AWWA M11 harness and C219 bolted sleeve-type joints. It can accommodate differential settlement and seismic movement in large-diameter piping systems and is comprised of Victaulic’s AGS Flexible Coupling Style W77. The couplings are self-aligning and provide a visual confirmation of proper assembly from the metal-to-metal bold pad contact. The joint is available in 14- to 78-inch DN350 to DN1950 sizes and is designed to be direct buried, utilizing epoxy coating compliant with NSF61 and AWWA C210 as well as stainless steel hardware. 610/559-3300; www.victaulic.com
