MFC-W Watertight Firestop Collars

Product Description

MFC-W Watertight Firestop Collars

The MFC-W Collar is a watertight, factory-manufactured, intumescent device for use as a 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 incorporates a rubber grommet which fits snugly around the pipe to ensure watertightness. MFC-W 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.
  • Provides watertightness up to 6 bar and gastightness up to 1 bar.
  • Solid design requires pipe to be inserted through the watertight grommet.
  • Flexible intumescent liner accommodates vibration and will not damage pipe.
  • Resistant to aging and weathering.
