Usa Industrials BULK-RS-H40-22 Buna-n Rubber Sheet

Product Description

The USA INDUSTRIALS BULK-RS-H40-22 is a stock-length Buna-N (nitrile) rubber sheet used for gasketing, sealing, vibration damping, and general fabrication across plumbing, HVAC, and industrial maintenance applications. The sheet measures 12 inches wide by 12 inches long and carries a Shore A durometer rating of 35 to 45, placing it in the soft-to-medium hardness range. Buna-N compound provides solid resistance to petroleum-based oils, fuels, and hydraulic fluids, making it a reliable choice wherever hydrocarbon exposure is a factor. The sheet weighs approximately 0.5 pounds and ships as a single piece.

This rubber sheet is suited for residential and light commercial applications where a field-cut gasket or seal is needed. Plumbers, HVAC technicians, and maintenance mechanics commonly use Buna-N sheet stock to fabricate custom gaskets for flanged connections, equipment mounts, and pipe penetration seals. Its temperature range of -20 degrees F to 170 degrees F covers most mechanical room and rooftop equipment environments. The black, unfaced sheet can be cut with standard shears, a utility knife, or a die punch to match the required profile.

Key Features

• Buna-N (nitrile) compound resists petroleum oils, fuels, and hydraulic fluids
• Shore A durometer of 35 to 45 for soft-to-medium compressibility
• Operating temperature range from -20 degrees F to 170 degrees F
• Tensile strength rated at 800 psi
• 12 inch x 12 inch stock size allows field fabrication without special tooling
• Sold as a single sheet with no minimum order beyond one unit

Compatibility

Designed as a general-purpose Buna-N rubber sheet stock suitable for fabricating gaskets, pads, and seals in plumbing, HVAC, and industrial maintenance applications where nitrile rubber compound is specified.

Installation Notes

Cut to the required shape using shears, a utility knife, or a gasket punch before installation. Shut off and depressurize any fluid system before replacing a gasket or seal fabricated from this sheet. Verify that the mating flange surfaces are clean and free of old gasket material prior to fitting the new piece. Consult applicable codes such as the IPC or IFGC for gasket material requirements on gas and plumbing systems.
