RectorSeal Metacaulk® Intumescent Sleeve 234 – 2" Pipe

Protect 2-inch plastic pipe penetrations with a fast, reliable, and code-compliant firestop solution. RectorSeal Metacaulk® Intumescent Sleeve 234 is a prefabricated intumescent sleeve designed specifically to simplify firestop installations around combustible pipe penetrations in fire-rated walls and floors. It provides dependable fire protection while significantly reducing installation time compared to traditional collars or wrap strips.

Manufactured with a durable galvanized steel shell lined with highly intumescent material, the sleeve rapidly expands when exposed to extreme heat, sealing the opening created as plastic pipes soften or burn away. The result is a secure fire barrier that helps prevent the spread of flames, smoke, and toxic gases throughout the building.

Designed for quick installation, the sleeve requires no complicated assembly, anchors, or special tools. It can be secured using fiberglass tape, hose clamps, or pop rivets, making it an excellent solution for contractors seeking faster installations without sacrificing performance. Ideal for commercial, industrial, healthcare, educational, and multifamily construction projects.
