The VALUE COLLECTION 31943863 is a closed cell silicone foam sheet used for gasketing, sealing, cushioning, and thermal or vibration isolation in industrial and mechanical applications. Measuring 12 inches wide by 12 inches long, this stock-length sheet features a plain, non-adhesive backing. Closed cell construction limits moisture and air infiltration, making it suitable for sealing applications where an open cell material would allow fluid passage. Silicone as the base material provides broad temperature resistance and flexibility, which is why it is a common choice for HVAC equipment gaskets, duct penetration seals, and equipment vibration pads.
This silicone foam sheet is appropriate for use in residential and commercial mechanical applications where a compressible, heat-resistant sealing material is required. Typical uses include fabricating custom gaskets for access panels, pipe penetration pads, flange seals, and vibration isolation mounts. HVAC technicians, pipefitters, and industrial maintenance trades commonly cut sheet foam stock to fit specific applications on-site. The 12 inch by 12 inch size provides adequate material for most single-gasket or small-pad fabrication tasks without material waste.
Designed as a general-purpose closed cell silicone foam sheet suitable for HVAC, mechanical, and industrial sealing and gasketing applications where a compressible, non-adhesive silicone sheet material is required.
Cut to size using a sharp utility knife or die-cutting tool on a stable flat surface. If bonding is required, apply a silicone-compatible contact adhesive to the plain backing surface. Ensure mating surfaces are clean and free of oil or debris before installation. No special certifications are required to install foam gasketing material, but always follow applicable equipment manufacturer instructions and local mechanical codes when using this material as a component in a sealed system.
