Change made to Lubrizol’s exclusive FBC™ System Compatible Program

CLEVELAND, October 15, 2015 - The Lubrizol Corporation's CPVC Piping Systems business has updated its FBC™ System Compatible Program with the addition of two freeze protection products to the approved products list and Insulation and Heat Trace categories on the Other Chemical Compatibility Topics list.

New Additions: Freeze Protection

  • Superior Oil Company - Superguard G38 and Superguard G48

Superguard G38 and Superguard G48 have been independently tested and shown to be compatible with Lubrizol's CPVC piping systems including FlowGuard Gold® Pipe and Fittings, BlazeMaster® Fire Sprinkler Systems and Corzan® Industrial Systems.

Update to the Other Compatibility Topics Page:

The following wording has been added to the Other Compatibility Topics page regarding Insulation and Heat Trace products:


  • Tubing insulation for use with CPVC should be fiberglass or foamed polyolefin (polyethylene). Foamed rubber tubing insulation may contain incompatible plasticizers and is not preferred. Foamed polyolefin insulation should not have any oil lubrication applied to the interior surface.

 Heat Trace

  • It is acceptable to heat trace FlowGuard Gold, BlazeMaster, and Corzan pipe and fittings provided the temperature of the heat tracing material does not exceed 180°F (82°C). Steam heat tracing should not be used. Chemical compatibility of the heat tracing material with CPVC should be confirmed with the product manufacturer. The heat tracing material should comply with all applicable codes and be installed per manufacturer's instructions.


Products qualify for the program by undergoing testing that demonstrates the product is compatible with FlowGuard Gold Pipe & Fittings, BlazeMaster Fire Sprinkler Systems and Corzan Industrial Systems.

Manufacturers of the program's products are committed to maintaining necessary product quality and agree not to change the chemical composition of the product without advance written notice. If there is a change in the chemical composition, manufacturers must re-submit their products in order to be included in the FBC System Compatible Program. Manufacturers must also submit their products to periodic testing to ensure the products remain chemically compatible. Because CPVC products are made with base resins having different molecular weights and varying chlorine contents and compound additives, the FBC System Compatible Program can verify chemical compatibility of products made with Lubrizol's FlowGuard, BlazeMaster and Corzan compounds with the ancillary products tested and added to the Lubrizol FBC™ System Compatible Program.

Products in the program display the FBC System Compatible mark on their labels. This mark quickly notifies installers that the product is chemically compatible with FlowGuard, BlazeMaster and Corzan CPVC products. The FBC System Compatible Program is in active use in the United States, Canada, Mexico, 25 European countries, the United Arab Emirates, India and China.
