- The SpecSeal® series SSC 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 SpecSeal® series SSC Firestop Collar is specifically sized to fit 1-1/2 in (38 mm), 2 in (51 mm), 3 in (76 mm) and 4 in (102 mm) trade sized pipes. When exposed to temperatures in excess of 320 deg F (160 deg C), the SpecSeal® series SSC collar molded insert begins to expand (intumesce) rapidly to form a dense, highly insulative char. Its free expansion ranges from 32x to 64x original (pre-expanded) volume. Expansion continues up to 1000 deg F (538 deg C).
