Firestop Collars

Intumescent pipe collar is a specialized fire-stopping component for pipe penetration openings. Under fire conditions, it expands rapidly to form dense fire-resistant layers, tightly wrapping pipes to seal gaps and block flame and smoke spread. Non-toxic and high-temperature resistant, it delivers reliable fire separation performance. Simple for installation, it fits various pipe sizes. Custom specifications are available, widely used in building fire protection systems to meet fire safety requirements for pipeline penetrations
