Grooved Couplings
Figure 774 Rigid Couplings
Tech Data Sheet: G142
The GRINNELL Figure 774 Grooved Rigid Coupling provides a rigid joint by firmly gripping along the full circumference of the pipe grooves. Figure 774 Grooved Rigid Couplings
are a proven dependable method of joining pipe and are an economical alternative to welding, threading, or using flanges. It is capable of pressures up to 34.5 Bar (500 psi) depending on pipe size and wall thickness.

* Maximum available gap between pipe ends. Minimum gap = 0.
† Maximum Pressure and End Load are total from all loads based on 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.
** Gold colour coded metric bolt sizes for 25mm - 300mm couplings are available upon request.
The Fig. 774 Standard Weight 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.
