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