MFC-G Large Diameter FRP/GRE/GRP Firestop Collars
The MFC-G Collar is a factory-manufactured, intumescent device for use as a FRP/GRE/GRP pipe penetration seal in fire-rated bulkheads and decks. It is comprised of a stainless steel body with a mild steel flange for easy weld attachment to the division, and can provide watertightness with a quick application of MFS Sealant. MFC-G Collars are lined with a molded, intumescent insert which rapidly expands to more than 60 times its original volume, containing fire to the point of origin and restricting the passage of smoke and hot gases.
