Buna-N rubber is a synthetic elastomer known for its resistance to petroleum-based oils, fuels, and hydraulic fluids, making it a reliable gasketing and sealing material across industrial, plumbing, and mechanical applications. This sheet has a Shore A durometer rating of 35 to 45, placing it in the soft-to-medium hardness range. It carries a tensile strength of 800 psi and is rated for continuous service from -20 degrees F to 170 degrees F. At 3.6 pounds, the sheet is dense and uniform, suitable for cutting custom gaskets, pads, or seals on the job.\u003c\/p\u003e\u003cp\u003eThis Buna-N rubber sheet is used in residential and commercial settings wherever oil-resistant sealing material is required. Common applications include custom-cut pipe gaskets, vibration isolation pads, valve seat material, flange seals, and wear strips. Plumbers, pipefitters, and industrial maintenance technicians typically source sheets like this when a standard pre-cut gasket is unavailable or when a specific shape must be field-fabricated. The 12 inch by 12 inch format provides a workable blank for most standard flange and fitting sizes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (nitrile) compound resists petroleum oils, fuels, and hydraulic fluids\u003c\/li\u003e\n\u003cli\u003eShore A durometer of 35 to 45 for soft-to-medium compressibility and conformability\u003c\/li\u003e\n\u003cli\u003eTensile strength of 800 psi for reliable performance under compression loading\u003c\/li\u003e\n\u003cli\u003eTemperature range of -20 degrees F to 170 degrees F suits a wide range of service conditions\u003c\/li\u003e\n\u003cli\u003eStock 12 inch x 12 inch size is ready to cut, punch, or die-cut to required shape\u003c\/li\u003e\n\u003cli\u003eBlack color is standard for Buna-N compound identification on the job\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose Buna-N rubber sheet suitable for field-fabricated gaskets, seals, and pads in oil-exposed or fuel-adjacent mechanical and plumbing systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and shaping of rubber sheet stock is typically performed by plumbers, pipefitters, or industrial mechanics using a sharp utility knife, hole punch, die-cutting tool, or gasket cutter. Always depressurize, drain, and lock out the system before replacing any gasket or seal. Verify that the rubber compound is chemically compatible with the specific fluid or gas in the system prior to installation. Follow applicable codes such as IPC or ASME B16.21 for gasket material selection on flanged connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile) Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShore A Durometer\u003c\/strong\u003e: 35 to 45\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTensile Strength\u003c\/strong\u003e: 800 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -20 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 170 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stock Length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: USA INDUSTRIALS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BULK-RS-H40-28\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"USA INDUSTRIALS","offers":[{"title":"Default Title","offer_id":67911585300786,"sku":"BULK-RS-H40-28","price":57.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a91f2b347429692a6e6a6fb1561e7906_334c903a-e7f9-4a34-a830-8ac0b10efb63.jpg?v=1791212905","url":"https:\/\/voomisupply.com\/products\/usa-industrials-bulk-rs-h40-28-buna-n-rubber-sheet","provider":"Voomi Supply","version":"1.0","type":"link"}
