FlowGuard Gold CTS CPVC pipe and fittings used in potable water systems and ReUze
®
CTS CPVC pipe and fittings used in
non-potable water systems are manufactured to the dimensions and specifications shown in ASTM D 2846. This product is
tan in color, and the pipe has the same outside diameter as copper tubing. Pipe up through nominal 2” size is manufactured
to a standard dimension ratio (SDR) of 11. The standard dimension ratio represents the ratio of the pipe O.D. to the pipe wall
thickness. Consequently, all of the SDR 11 CPVC sizes have the same pressure rating.
