VSH Shurjoint standard rigid coupling FF 48.3 red ISO

group: 7771E

item: 177710015002

The VSH Shurjoint Model 7771 Standard Rigid Coupling is the ideal choice for risers, mechanical rooms or other applications where rigidity is required. The tongue and groove design and mechanisms provide a rigid connection reducing and or eliminating flexural and torsional loads. The Model 7771 coupling sizes 1½” - 12” (DN40–DN300) are comprised of two identical housing segments, sizes 14”-18” (DN350–DN400) are comprised of three identical segments and sizes 20” - 24” (DN500–DN600) are comprised of four identical segments. All include an EPDM rubber gasket and plated track bolts and nuts. Housing segments are supplied with our standard painted finishes, i.e. orange or red. Optional finishes such as hot dipped zinc galvanized and custom epoxy coatings are available.
