Usa Industrials BULK-RS-H40-276 Buna-n Rubber Strip 40A

Product Description

The USA INDUSTRIALS BULK-RS-H40-276 is a stock-length Buna-N (nitrile) rubber strip rated at 40 Shore A durometer. At 4 inches wide and 60 inches long, this flat strip is used to create seals, gaskets, vibration pads, and protective liners in mechanical, plumbing, and industrial applications. The 40 Shore A hardness delivers a soft, conformable feel suitable for static sealing and cushioning work. Tensile strength runs from 800 to 1000 psi, and the strip handles temperatures from -20 degrees F up to 170 degrees F, making it a reliable choice across a broad range of service conditions.

This Buna-N rubber strip suits residential and light commercial applications where oil, fuel, or water resistance is required. Common uses include cut-to-fit gaskets for flanged pipe connections, equipment vibration isolation pads, door and hatch seals, and surface protection in pump or compressor installations. Plumbers, pipefitters, HVAC technicians, and maintenance mechanics regularly use stock-length rubber strip to fabricate custom seals and spacers on the job without waiting for custom-cut parts.

Compatibility

Designed as an OEM-style and fabrication replacement strip for applications requiring a soft Buna-N rubber material in a 4-inch-wide, 60-inch stock length format.

Installation Notes

This strip is typically cut to length or shape using a sharp utility knife or die-cutting tools on a flat, stable surface. When used as a gasket or seal, ensure mating surfaces are clean and free of debris before installation. Follow applicable codes such as the IPC or IFGC when using rubber strip in pipe or equipment sealing applications. No adhesive is required for compression-style installations, but contact cement may be used for bonded applications per project specifications.
