SpecSeal® Range-Taking Firestop Collars (RTC) are factory manufactured devices designed to seal plastic pipes penetrating through fire resistance rated walls and floors. SpecSeal® RTC Collars are comprised of a heavy gauge metal collar housing a molded intumescent insert. The adjustable collar is designed to allow a single collar to fit 3 in (89 mm) and 4 in (114 mm) trade size pipes and corresponding 3” (102 mm) and 4” (127 mm) couplings. When exposed to temperatures in excess of 320°F (160°C), the SpecSeal® Range-Taking Firestop Collars’s molded insert begins to expand (intumesce) rapidly to form a dense, highly insulative char. Free expansion ranges from 32x to 64x original (pre-expanded) volume. Expansion continues up to 1,000°F (538°C).

  • Adjustable - one collar fits 3” (89 mm) pipe, 3” (102 mm) coupling, 4” (114 mm) pipe, and 4” (127 mm) coupling
  • Rapid expansion - closes off burning pipes quickly
  • Small profile - use it in all the tight spots
  • Flexible & durable - no loose flakes (eye hazards)
  • Water resistant - no water soluble or hygroscopic ingredients
  • Economical - lower installed cost
  • High volume char - expands up to 60 times
