The Grinnell Stainless Steel System is designed for joining 2" to 12" (54,0mm to 206,4mm) stainless steel piping, schedules 5, 10, and 40.
The Figure 472 coupling patented Universal Tongue and Groove design makes for a trouble free installation and allows the coupling housing to grip along the full 360ยบ of circumference of the pipe. This results in a more rigid and stronger connection. Coupling housings have gripping teeth in sizes 2" to 4" (54,0mm to 101,6 mm) that makes the Figure 472 perfectly suited for installations where the likelihood of rotation is greatest.
The Grinnell Stainless Steel Couplings are made of 316L and are generally compatible with grade 304 stainless steel material.
