MODEL SS-7 STAINLESS STEEL RIGID COUPLING

The Model SS-7 Stainless Steel Rigid Coupling is the ideal coupling for use with Sch. 5S, Sch. 10S or Sch. 40S stainless steel pipe where a rigid connection is desired.  The Model SS-7 features a tongue and groove mechanism and a heavy duty bolt pad design resulting in a positive rigid connection.  The SS-7 has no built-in teeth that could harm light wall pipe or fittings.  The SS-7 couplings are comprised of two identical CF8 (304) or CF8M (316) housing segments, EPDM gasket and stainless steel track bolts and heavy duty nuts. 

* The working pressure shown is based on roll-grooved Sch. 40S pipe.  For other pipe schedules, see the below table on page 2.

† 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”/DN20 – 3½”/DN90; 25% for 4”/DN100 and larger to compensate for jobsite conditions.
