STI SpecSeal 3 x 4 inch Range-Taking Firestop Collar RTC350

SpecSeal Range-Taking Firestop Collars (RTC) are factorymanufactured 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 inches (89 mm) and 4 inches (114 mm) trade size pipes and corresponding 3 inches (102 mm) and 4 inches (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).
