Usa Industrials BULK-RS-HUS70-245 Buna-n Rubber Sheet

Product Description

The USA INDUSTRIALS BULK-RS-HUS70-245 is a stock-length Buna-N (nitrile) rubber sheet used as a sealing, gasketing, and vibration-dampening material in HVAC, plumbing, and industrial applications. It measures 0.125 inches thick, 12 inches wide, and 24 inches long, with a plain backing and a Shore A durometer rating of 65 to 75, placing it in the medium-firm hardness range. The sheet weighs approximately 2 pounds and resists oils, fuels, and many common fluids, making it a practical cut-to-fit source material for fabricating custom gaskets, pads, and seals. Licensed tradespeople and maintenance technicians typically cut this sheet to size using standard utility knives or die-cutting tools.

This Buna-N rubber sheet is suited for residential and light commercial settings where a durable, oil-resistant elastomer is needed. Common applications include fabricating HVAC equipment vibration isolation pads, pipe flange gaskets, pump seals, and general-purpose sealing strips. The black plain-backed sheet format allows tradespeople to trace, score, and cut custom profiles on the job or in the shop. The rated temperature range of -20 degrees F to 180 degrees F covers most standard mechanical room and rooftop equipment environments.

Key Features

• Buna-N (nitrile) compound resists oils, fuels, and petroleum-based fluids

• Tensile strength of 2,500 psi for durable cut gasket and pad fabrication
• Operating temperature range of -20 degrees F to 180 degrees F
• Plain backing allows direct cutting, tracing, and bonding without removal of liner
• Stock sheet format: 12 inches wide by 24 inches long, ready to cut to size

Compatibility

Designed as a cut-to-fit rubber sheet material for fabricating gaskets, seals, and isolation pads in HVAC, plumbing, and general mechanical applications where oil-resistant nitrile rubber is specified.

Installation Notes

A licensed HVAC technician, plumber, or qualified maintenance mechanic typically installs components fabricated from this sheet. Always shut down and de-energize or depressurize the equipment before replacing any gasket or seal. Use a sharp utility knife, hole punch, or die cutter against a firm cutting surface to achieve clean edges. Consult applicable mechanical or plumbing codes for gasket material requirements before installation in pressurized systems.
