Usa Industrials BULK-RS-S50CFDA-4 Silicone Rubber Sheet

Product Description

The USA INDUSTRIALS BULK-RS-S50CFDA-4 is a stock-length silicone rubber sheet measuring 12 inches wide by 12 inches long with a clear finish. It carries a Shore A durometer rating of 45 to 55, placing it in the medium-soft range suitable for gasketing, sealing, and cushioning applications. Rated for continuous service from -80 degrees F to 450 degrees F, this sheet maintains flexibility and integrity across a wide thermal range. Tensile strength is rated at 850 psi. The sheet weighs approximately 0.3 pounds. Fabricators, maintenance technicians, and trade professionals cut this material to size for custom gaskets, seals, vibration dampers, and insulating pads.

This silicone rubber sheet suits residential and commercial applications where thermal resistance, weatherability, and compression recovery are required. Common uses include HVAC duct sealing, equipment vibration isolation, pump and compressor gasketing, and general-purpose sealing in plumbing and mechanical systems. Its clear color makes it easy to inspect for cuts or deformation after installation. The stock 12 inch by 12 inch format is ready for bench fabrication without additional sizing from a large roll.

Installation Notes

Cut to required shape and size using a sharp utility knife, die cutter, or scissors rated for rubber sheet stock. Ensure mating surfaces are clean and free of oil, debris, or old gasket material before installing a fabricated gasket or seal. For compressed gasketing applications, follow the equipment manufacturer's torque sequence guidance for fasteners. Silicone rubber is not compatible with all fluid media - verify chemical compatibility with the service fluid before installation.
