Lubrizol Corporation”s High-Pressure Flange Kit is specifically designed for use with a Corzan CPVC one-piece flange to connect to pumps, valves or other transitions. The kit combined with CPVC one-piece flanges provides a connection with the same pressure bearing capability as the rest of the CPVC piping system. This means the flanged joint is no longer limited to the 150 PSI rating of typical CPVC flanges.The kit includes a Garlock Stress Saver XP gasket, certified by NSF International to ANSI/NSF Standard 61. The kit also includes the necessary installation hardware and a metal backing ring, which allows more torque on the bolts without concerns of damaging the CPVC flange. The assembled flange system meets the pressure bearing requirements as defined by ASTM F1970.
