The Dresser Style 711 provides a line of bolted couplings that seals and restrains making reliable joints on any combination of Steel and P. E. pipe. A “pressure seal” prior to the metallic gripping mechanism locks the pipe against pullout. This patented engineering breakthrough offers the capability of a “seal plus pipe restraint” pipe joint with minimal components. The convenience of an assembled stab product also eliminates the disassembly of any components, assuring that all of the components are properly installed.
