MFC Traditional Firestop Collars

The MFC Collar is a factory-manufactured device for use as a 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 may be split for quick installation around existing pipes. MFC 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.

  • Heavy gauge, chromium rich 316 stainless steel construction.
  • Resistant to aging and weathering, no soluble or hygroscopic ingredients.
  • Designed for high volume of char and rapid expansion.
  • Retrofits around existing metallic and non-metallic pipes.
  • Available in many common sizes and won’t damage outside of pipes.
