Everkem Intumescent Firestop Collars

The Everkem Diversified Products Intumescent Firestop Collar CLR-1 is a 1.5" one-piece fire protection device designed for plastic pipe and conduit penetrations through fire-rated floor and wall assemblies. This ready-to-use collar features intumescent technology that expands when exposed to heat, sealing off penetrations to maintain fire ratings. The collar meets ASTM-E814 standards and carries UL classification for reliable fire protection performance.

Installation is straightforward with this pre-manufactured collar system, reducing labor costs compared to field-applied alternatives. The intumescent material activates at elevated temperatures, expanding to close off the penetration and prevent fire and smoke passage. Made in the USA, this collar incorporates EcoSeal technology for enhanced environmental performance while maintaining full compliance with fire safety codes. The UL classified design ensures consistent performance in fire-rated assemblies.

These collars work effectively in commercial and residential construction where plastic piping systems penetrate fire-rated walls or floors. The 1.5" size accommodates standard small-diameter pipes and conduits commonly found in electrical and plumbing installations. The collar integrates seamlessly with other fire inspection compliance systems to maintain building fire ratings.
