FBC™ System Compatible Program

Eliminate chemical compatibility questions when using Corzan® CPVC products.

No matter what materials you use, ensuring compatibility is essential. 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.

While Corzan® CPVC is immune to corrosion, pitting and scaling, installers need to be sure they are using ancillary construction products that are compatible with Corzan CPVC. To ease the burden associated with researching and selecting accompanying construction products, Lubrizol developed the FBC™ System Compatible Program. This exclusive program, developed by Lubrizol, removes the guesswork associated with chemical compatibility.

Before selecting ancillary products, find products known to be compatible with Corzan Pipe and Fittings. Each listed product undergoes formulation screening and rigorous physical testing in contact with Lubrizol CPVC samples at a third-party laboratory.

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.

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's FlowGuard®, BlazeMaster®, Corzan®, and AquaRise® made with TempRite® Technology CPVC piping systems. 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 brands of FlowGuard®, BlazeMaster®, Corzan®, and AquaRise® made with TempRite® Technology CPVC piping systems. 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 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 AquaRise® made with TempRite® Technology CPVC piping systems.
