Lubrizol Announces Updates to the Exclusive FBC™ System Compatible Program

CLEVELAND, April 21, 2014 The Lubrizol Corporation’s CPVC business announces updates to its FBC™ System Compatible Program with the addition of two new products and an addition to the Incompatible Products list.

New Additions:

  • Hilti CFS-S SIL SL Firestop Sealant – a self-leveling, single-component, silicone-based firestop sealant for use with through-penetrations as well as construction joints in floors.
  • Hilti CFS-S SIL GG Firestop Sealant – a silicone-based firestop sealant that provides maximum movement in fire-rated joints, and seals through-penetration applications.

Both Hilti firestop sealants have been independently tested and shown to be compatible with Lubrizol’s CPVC piping systems, including FlowGuard® Pipe & Fittings, BlazeMaster® Fire Sprinkler Systems and Corzan® Industrial Systems. For more information about these two Hilti firestop sealants, visit its website at: For more information about these or other products within the FBC System Compatible Program, visit the FBC System Compatible website at:

Update to the Incompatible Product List:

  • The Incompatible Product list has been updated to include Gyproc Sealant. Gyproc is a caulk manufactured by British Gypsum.

Products qualify for the program by undergoing testing that demonstrates the product is compatible with FlowGuard 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 and 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 only with the products with which they have been tested.

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.
