* Maximum available gap between pipe ends. Minimum gap = 0.
† Maximum Pressure and End Load are total from all loads based on standard weight steel pipe.
Pressure
ratings and end loads may differ for other pipe
materials and/or wall thicknesses. Contact a GRINNELL Sales Representative for details.
‡ Max End Gap is for cut grooved standard weight pipe. Values for roll grooved pipe will be half that of cut grooved.
• Only available in ANSI bolt sizes.
The Fig. 772 Heavy Duty Rigid Coupling does not provide compensation for pipe system expansion and/or contraction associated with pipe system
temperature changes.
For information on alternative sizes, contact a GRINNELL Sales Representative.
See page 17 for coupling specifications and pages 116 - 127 for gasket information.
For instructions on part numbers, ordering information, and availability, refer to page 13 or contact a GRINNELL Sales Representative.
