3 in STI SpecSeal LCC Intumescent Firestop Collars

The SpecSeal Series LCC 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 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 SpecSeal Series LCC Collars 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).
