LCC Series 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 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 1,000°F (538°C).
