STI SpecSeal SSP Firestop Putty Tube | 36 Cubic In

The STI SpecSeal® SSP Firestop Putty Tube | 36 Cubic Inches is a moldable, intumescent firestop solution designed to seal cable and conduit penetrations in fire-rated walls and floors. This flexible firestop putty helps prevent the spread of flames, smoke, and toxic gases, maintaining the integrity of fire-rated building assemblies in commercial and institutional environments.

Formulated with intumescent technology, the putty expands when exposed to heat, filling gaps and openings around cables, conduits, and other penetrations. Its pliable consistency allows for quick hand application, making it easy for installers to seal irregular openings and cable bundles commonly found in telecommunications rooms, data centers, electrical closets, and structured cabling pathways.

The 36 cubic inch tube format provides additional material for sealing larger openings or multiple penetrations while still allowing the putty to remain reusable and removable. This makes it ideal for environments where cables may need to be added, removed, or reconfigured over time.
