Usa Industrials BULK-RS-S40-26 Silicone Rubber Sheet

Product Description

The USA INDUSTRIALS BULK-RS-S40-26 is a stock-length silicone rubber sheet cut to 12 inches wide by 12 inches long with a red color designation and a Shore A durometer rating of 35 to 45. This soft-to-medium hardness sheet delivers a tensile strength of 650 psi and maintains flexibility across a wide service temperature range of -60 degrees F to 500 degrees F. It is used wherever a compressible, heat-resistant elastomeric sheet material is required for gasketing, padding, sealing, or fabrication work in industrial and mechanical service environments.

This silicone sheet is suited for applications in HVAC, plumbing, electrical enclosures, and general industrial settings where thermal extremes, vibration, or chemical exposure demand a durable elastomer. Its low durometer makes it appropriate for static sealing and cushioning applications. Technicians and fabricators typically cut it to size for custom gaskets, isolation pads, duct seals, or access panel seals. The 12-inch by 12-inch format is a practical single-piece stock size for field fabrication.

Key Features

• Shore A durometer of 35 to 45 for soft-to-medium compressibility suitable for gasketing and sealing
• Tensile strength of 650 psi for reliable tear resistance during cutting and installation
• Service temperature range from -60 degrees F to 500 degrees F suits high-heat and cold-climate applications
• Stock-length 12-inch x 12-inch format ready for field cutting and custom fabrication
• Red color for easy visual identification of silicone material in multi-material inventories

Compatibility

Designed as a general-purpose silicone rubber sheet for use in HVAC, plumbing, electrical, and industrial fabrication applications requiring a heat-resistant, flexible elastomeric material.

Installation Notes

Installation is typically performed by HVAC technicians, pipefitters, electricians, or industrial maintenance personnel. Use a sharp utility knife, die, or scissors rated for elastomeric materials to achieve clean cuts. Ensure mating surfaces are clean and free of oil, debris, or old gasket material before seating the sheet. Follow applicable codes and equipment manufacturer guidelines when using this material as a gasket or seal in pressurized or high-temperature systems.
