K-FLEX K-FIRE COLLAR-E

K-FLEX K-FIRE COLLAR-E is an intumescent firestop collar designed for plastic pipe penetrations through fire-separating walls and floors. When exposed to fire, the intumescent material expands, compresses the softening pipe and seals the resulting opening. This action helps maintain the fire integrity and insulation performance of the penetrated construction.
