Incompatible Products

To avoid damage to the pipe and fittings, ancillary construction products coming into direct contact with FlowGuard®, BlazeMaster®, or Corzan® piping systems must be chemically compatible. Lubrizol recommends that the compatibility of ancillary products should be confirmed with that product’s manufacturer prior to use.

The following products have been found to be incompatible with FlowGuard®, BlazeMaster®, and Corzan® piping systems. Please note: a product’s absence from this list does not mean that it is compatible. Products are designated with superscripted numerals in this list to clarify the known compatibility hazards associated with them, as follows:

1 These products were reported to have been used at the site of one or more failed piping systems, and upon further investigation were found to contain the same ingredient(s) which were identified as having caused or contributed to the reported failure.
2 These products have been determined to be incompatible based on laboratory testing conducted by Lubrizol.
3 These products have been determined to be incompatible based on compositional information found in the manufacturer’s labeling or published literature. One or more ingredients reported by the manufacturer is the same as or chemically similar to ingredients identified as having caused or contributed to piping system failure with similar products (the products designated with a 1).
4 These products have recommendations in their manufacturer’s published literature not to use them with CPVC. This may not necessarily reflect their compatibility status. They are nevertheless listed here because, as reported by the manufacturer, they should not be used with CPVC.

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®, and Corzan® 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, and Corzan 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, and Corzan.
