FlowGuard Gold^® and Corzan^® pipe and fittings are made from a specialty plastic known chemically as chlorinated polyvinyl chloride (CPVC). FlowGuard Gold and Corzan CPVC is the result of new technology that ensures increased product toughness year round. FlowGuard Gold and Corzan water distribution systems are assembled with readily available, inexpensive tools. Solvent cemented joints – proven with more than 40 years of successful service history – assure the reliability of a FlowGuard Gold and Corzan plumbing system.

FlowGuard Gold pipe and fittings are available in copper tube sizes (CTS) from ½" to 2". Corzan^® CPVC pipe and fittings can be utilized in systems requiring larger size pipe and fittings. Corzan pipe and fittings are available in iron pipe sizes (IPS) from ½” to 24” and greater in diameter. Fittings are available for easy transition from the IPS Corzan CPVC to CTS FlowGuard Gold CPVC.

Lubrizol produces and sells CPVC compounds to licensed manufacturers of FlowGuard Gold pipe and fittings and Corzan pipe and fittings.
