VSH Shurjoint heavy duty flexible coupling (2 x groove), Fluoro-elastomer gasket

group: 7707O

7707O is the designation for model 7707 with a Grade O fluoro-elastomer gasket. The VSH Shurjoint Model 7707 Flexible Coupling is designed for use in a variety of general piping applications of moderate or high pressure services. Working pressure is usually dictated by the wall thickness and rating of the pipe being used. The Model 7707 couplings feature flexibility that can accommodate misalignment, distortion, thermal stress, vibration and noise and also resist seismic tremors. The utilization of Model 7707 couplings can accommodate a curved layout.
