Sealant - Self-Seal® Intumescent Silicone Firestop Collar Ring Type-SSC 3IN 10/PK

Self-Seal® Type-SSC Intumescent Silicone Firestop Collar is a pre-fabricated collar designed to seal combustible pipe penetrations in fire-rated walls and floors. The galvanized metal collar houses a moulded silicone rubber intumescent ring. The silicone composition exhibits excellent performance stability, and when exposed to temperatures above 150°C (300°F), it will begin to expand. As the pipe softens and collapses under fire conditions, the silicone composition will rapidly intumesce to fill the void with a patented char composite that contains expanded graphite. The collar is pre-fabricated to fit 1-1/2” (38 mm), 2” (51 mm) and 3” (76 mm), and 4” (102 mm) trade sized pipes.
