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% for3”; 25% for 4” and larger to compensate for
** Deflection or angular movement is the maximum value that a
coupling allows under no internal pressure.
