MFC-G Large Diameter GRE/GRP Firestop Collar

Product Description

MFC-G Large Diameter GRE/GRP Firestop Collars

The MFC-G Collar is a factory-manufactured, intumescent device for use as a 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.

  • Fits most pipe sizes from 302 mm to 746 mm
  • Provides watertightness up to 4 bar and gas-tightness up to 1 bar, when sealed with MFS sealant
  • Rapid intumescent expansion under fire conditions quickly seals off the path for fire, gases, and smoke
  • Stainless steel body with mild steel flange for weld-attachment or steel screws
  • Flexible intumescent liner accommodates vibration and will not damage pipe
  • Resistant to aging and weathering
