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 fire-stop collar is specifically sized to fit 1-1/2, 2, 3 and 4 Inch trade sized pipes. When exposed to temperatures in excess of 320 deg F (160 deg C), the SpecSeal® series LCC Collar’s 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 1000 deg F (538 deg C).
