Firestop Caulk. Seals service penetrations in fire-rated walls and floors. Cured red silicone rubber composition provides excellent performance stability and provides a pressure tight seal, which prevents the spread of fire, smoke and toxic gases through service penetrations. When exposed to fire conditions, the silicone composition will quickly expand to fill the void with a patented char composite that contains expanded graphite. Silicone will expand when exposed to temperatures in excess of 300º F (150º C). Suitable for AB/PVC, flexible foam insulated copper pipe, PEX process and supply tubing penetrations, metallic pipe and electrical cable penetrations. Cartridge fits manual or air-operated caulking guns.
