The Walraven Pacifyre® MK II Fire Collar (M) is a high-performance fire stopping solution designed for plastic pipe penetrations through fire-rated walls and floors. This specific collar is engineered for pipes with an outer diameter ranging from 258mm to 260mm. Featuring a robust stainless steel casing and advanced intumescent material, it expands rapidly when exposed to heat, sealing off the penetration and preventing the spread of fire and smoke for up to 240 minutes (EI 240, E 240). Its split design allows for easy installation around existing pipework, making it a versatile and essential component for passive fire protection systems.
