Intumescent Pipe Collars

Quick Overview

Prefabricated device with precured dry intumescent designed for the circumference of open and closed through-penetrations diameters from 1 & 1/2? up to 6? (38 – 152 mm), with securing interlocking tab mechanism for easy installation. Metacaulk Intumescent Collars expand when exposed to heat, forming a refractory char that tightly seals to prevent the spread of flames, smoke, and toxic fumes. These collars are economical and easy to install, saving on labor and significantly reducing time and expense compared to other methods. They fit in limited access areas and require no measurement of material. Additionally, they are compatible with FBC Systems.
