Figure 472 Stainless Steel Rigid Couplings
Tech Data Sheet: G560
The GRINNELL Figure 472 Rigid Coupling is made of cast 316 stainless steel and is capable of pressure up to 41.4 Bar (600 psi).
The GRINNELL Figure 472 Patented Coupling universal tongue- and-groove design allows the housing to grip along the full 360° of circumference of the pipe. Sizes 32mm – 100mm (1 1⁄4" – 4") have gripping teeth to prevent rotation during installation.

Figure 472 Rigid Couplings have an Anti-Rotation Feature of “gripping teeth” along the coupling keys in sizes 1 1⁄4" - 4" (32mm - 100mm ),
making the Figure 472 perfectly suited for installations where the likelihood of rotation is greatest.
* Maximum available gap between pipe ends. Minimum gap = 0.
† Maximum Pressure and End Load are total from all loads based on standard weight stainless steel pipe. Pressure ratings and end loads may differ for other pipe materials and/or wall thickness. Contact a GRINNELL Sales Representative for details.
‡ Max end gap is for cut grooved standard weight stainless steel pipe. Values for roll grooved pipe will be half that of cut grooved. ** Contact a GRINNELL Sales Representative for availability of inch bolt sizes vs. metric bolt sizes.
For information on alternative sizes, contact a GRINNELL Sales Representative.
See page 95 for stainless steel coupling specifications and pages 116 - 127 for gasket information.
Note: The Fig. 472 Stainless Steel Heavy Duty Rigid Coupling does not provide compensation for pipe system expansion and/or contraction associated with pipe system temperature changes.
For instructions on part numbers, ordering information, and availability, refer to page 13 or contact a GRINNELL Sales Representative.
