Utilizing a heavy gauge galvanized metal collar to house a molded intumescent insert, the STI LCC Firestop Collar is specifically sized to fit 1-1/2˝, 2˝, 3˝, and 4˝ (38mm, 51mm, 76mm and 102 mm) trade sized pipes. When exposed to temperatures in excess of 320°F (160°C), the STI LCC 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).

  • Easy installation – uses STI’s quick closure design.
  • Compact profile – use it in all the tight spots!
  • Water-resistant – no water soluble or hygroscopic ingredients.
  • Fast-acting expansion (up to 60X) – to seal off burning pipes.
  • Safe for contact with plastics.
Applications
  • Combustible penetrants (factory manufactured).
  • Protects a variety of plastic pipes – PVC, PVC Foam Core (ccPVC), CPVC, ABS, and ABS Foam Core (ccABS).
  • Vented (DWV) and closed (electrical conduit and water supply) installations.
