Corzan® CPVC and the FBC™ System Compatible Program

Ensuring compatibility between piping material and ancillary products is essential to the health and longevity of the system. With metal piping, the industry knows to avoid contact between dissimilar metals to avoid galvanic corrosion. For generations, plumbers have known that copper must be protected when installed in concrete or high salinity environments because of corrosion concerns. Lubrizol developed the FBC™ System Compatible Program to ease the burden of researching and selecting construction products to accompany its CPVC offerings, including Corzan® CPVC.

The FBC™ System Compatible program helps installers be sure they are using ancillary construction products compatible with Corzan CPVC. The exclusive program removes guesswork and is another reason to spec Corzan CPVC, along with its immunity to corrosion, pitting and scaling.

To qualify for inclusion in the FBC™ System Compatible Program, the manufacturer of auxiliary construction products must agree to:

  • Submit their products for testing by a third-party lab.
  • Not alter the tested formulation.
  • Have their manufacturing facility audited annually by the third-party lab.

Each listed product undergoes formulation screening and rigorous physical testing in contact with Lubrizol CPVC samples at a third-party laboratory. Accepted products are given the right to display the FBC™ System Compatible mark on their labels.

Legal Disclaimer

The FBC™ System Compatible Program is a resource made available to manufacturers of ancillary products intended to be used with CPVC to help determine whether a product is chemically compatible with Lubrizol Advanced Materials' FlowGuard®, BlazeMaster®, Corzan®, and products made with TempRite® Technology. Other manufacturers and/or brands of CPVC piping have not been tested as part of the FBC™ System Compatible Program. The FBC™ System Compatible program is, therefore, only applicable to the chemical compatibility of ancillary products with the Lubrizol Advanced Materials brands of FlowGuard®, BlazeMaster®, Corzan®, and products made with TempRite® Technology. This distinction is made because every brand of CPVC piping is made with unique compounds, some of which may contain resins with different molecular weights and varying chlorine content. These characteristics directly impact the performance of the resulting product. Similarly, various CPVC products contain different performance additives. This too affects the performance characteristics of the ancillary product. For these reasons, Lubrizol Advanced Materials has no responsibility for any failures occurring as a result of using products in the FBC™ System Compatible Program with CPVC products other than FlowGuard®, BlazeMaster®, Corzan®, and products made with TempRite® Technology.
