Usa Industrials BULK-RS-S40WFDA-32 Silicone Rubber Sheet

Product Description

The USA INDUSTRIALS BULK-RS-S40WFDA-32 is a white silicone rubber sheet with a pressure-sensitive adhesive backing, measuring 12 inches wide by 12 inches long and 0.187 inches thick. It carries a Shore A durometer rating of 35 to 45, placing it in the soft-to-medium hardness range suitable for gasketing, sealing, and vibration damping applications. The material handles a continuous service temperature range from -20 degrees F to 500 degrees F and delivers a tensile strength of 640 psi. HVAC technicians, plumbers, and industrial maintenance professionals use this sheet stock to fabricate custom gaskets, pads, and seals on the job or in the shop.

This silicone sheet is suited for residential and light commercial HVAC systems, plumbing assemblies, and general industrial applications where thermal resistance and flexibility are required. The adhesive backing allows the sheet to be positioned and held in place during installation without additional fasteners or adhesive compounds. It is commonly cut to size using a knife, die, or punch press to produce custom gaskets, insulation pads, access panel seals, and vibration isolators. Stock-length format makes it practical for single-piece fabrication jobs.

Installation Notes

This sheet is typically cut by HVAC technicians, plumbers, or maintenance professionals using a straight knife, scissors, or punch die. Always power down or isolate the system before replacing gaskets or seals. Ensure mating surfaces are clean and free of debris before applying the adhesive-backed sheet. Follow applicable codes and equipment manufacturer guidelines when fabricating replacement seals for pressure-bearing or high-temperature assemblies.
