MODEL 7707A HEAVY DUTY FLEXIBLE COUPLING
The Model 7707A 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 7707A couplings feature flexibility that can accommodate misalignment, distortion, thermal stress, vibration and noise and also resist seismic tremors. The utilization of Model 7707A couplings can accommodate a curved layout. See Typical Applications – Flexible Couplings on Shurjoint cutsheet
The Model 7707A couplings are comprised of two housing segments, EPDM gaskets and plated track bolts and nuts. Housing segments are supplied with our standard painted finishes, i.e. orange or RAL3000 red. Optional finishes such as hot dipped zinc galvanized and epoxy coatings are also available.
* Working Pressure is based on roll grooved standard wall carbon steel pipe.
† Allowable Axial Displacement and Angular Movement (deflection) figures are for roll grooved standard steel pipe. Values for cut grooved pipe will be double that of roll grooved. These values are maximums; for design and installation purposes these figures should be reduced by: 50% for ¾” – 3½”; 25% for 4” and larger to compensate for jobsite conditions.
** Deflection or angular movement is the maximum value that a coupling allows under no internal pressure.
