7707N Heavy Duty Flexible Coupling

MODEL 7707N HEAVY DUTY FLEXIBLE COUPLING

The Model 7707N Heavy Duty Flexible Coupling is designed for use in a variety of general piping applications of moderate or high pressure services.   The Model 7707N couplings feature flexibility that can deal with misalignment, distortion, thermal stress, vibration and noise and also resist seismic tremors.  With the use of Model 7707N couplings you can even design a curved layout.  See Typical application – Flexible Couplings on Shurjoint Data Sheet #B-19.

The Model 7707N couplings sizes 14” – 26” (350 mm – 650 mm) are com­prised of two identical ductile iron housing segments, an EPDM rubber gasket and one or two bolts at each segment joint to ensure a positive connection and seal.

* 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 given is the maximum value that a coupling allows. When using the given maximum angles for a curved layout, proper bracing should be used to counter pressure thrust that will occur when the system is pressurized. Flexible couplings can be used for angular movement and or thermal expansion, though please note individual coupling(s) cannot be used to their maximums for both types of movement within a system at the same time.
