Unit Of Measure:

The Rectorseal MetaCaulk Intumescent Fire Collar is a factory-manufactured device designed to protect plastic pipes penetrating fire-rated walls and floors. Utilizing a heavy gauge galvanized metal collar to house a molded intumescent insert, the MetaCaulk Collar is specifically sized to fit 1-1/2", 2", 3", and 4" trade sized pipes. When exposed to temperatures in excess of 320°F (160°C), the MetaCaulk Collar’s molded insert begins to expand (intumesce) rapidly to form a dense, highly insulative char. Its free expansion ranges from 32-64 times original (pre-expanded) volume. Expansion continues up to 1,000°F (538°C).  PVC Firestop Collars should be installed on any plastic pipe that penetrates a fire-rated wall, ceiling, or floor.

Common Applications:

  • Radon Mitigation Piping (through garage wall/ceiling)
  • Central Vacuum Systems
  • PVC Drainlines
  • Plastic Electrical Conduits
  • PVC Sewer Vents
