7706 Reducing Coupling Download PDF



The Model 7706 Reducing Coupling allows direct reduc­tion on a piping run and eliminates the need for a concentric reducer and couplings.  The specially de­signed rubber gasket prevents the smaller pipe from telescoping into the larger pipe during vertical installa­tion.  All 7706 couplings are comprised of two identical hous­ing segments, EPDM rubber gasket 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 custom epoxy coatings are avail­able. 

* Working Pressure is based on roll- or cut-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.
