Rated at 70 Shore A hardness, this O-ring is designed for static and dynamic sealing applications where contact with petroleum-based fluids is expected. The Buna-N compound is the most widely used elastomer in fluid sealing, offering reliable compression set resistance along with strong tear and abrasion resistance. Licensed plumbers, HVAC technicians, and hydraulic system technicians regularly specify this material for general-purpose sealing across a broad temperature range.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in residential and commercial plumbing, HVAC refrigerant circuits, hydraulic fittings, fuel systems, and pneumatic equipment wherever a Dash 103 cross-section seal is required. Its compatibility with petroleum products makes it a go-to choice for valve stems, pump housings, fittings, and fluid connectors in both new construction and maintenance and repair applications. The part ships in a package quantity of 100, making it practical for stocking in a service van or shop inventory. It should not be stored in direct sunlight or near motors or other electrical equipment that may generate ozone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile) compound offers excellent resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating provides a firm, reliable seal under compression\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F suits most HVAC and plumbing environments\u003c\/li\u003e\n  \u003cli\u003eRound cross section conforms to SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eStrong tear and abrasion resistance extends service life in dynamic applications\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 100 supports shop stocking and fleet maintenance needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products and suitable for use in systems and fittings requiring a Dash 103 O-ring per SAE and MIL-Spec dimensional standards.

Always depressurize and isolate the system before removing or replacing any O-ring seal. Lightly lubricate the O-ring with a compatible fluid or grease before seating to prevent tearing during installation. Do not expose the installed O-ring or stored inventory to ozone sources such as electric motors or direct sunlight, as ozone degrades Nitrile compounds over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 103\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.094 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.281 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.094 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (Hard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Fluids\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZMSCH70103\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695227994418,"sku":"ZMSCH70103","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3454e8b732504ab16e488c90bc0242.jpg?v=1788332875","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70103-o-ring-dash-103-nitrile-buna-n","provider":"Voomi Supply","version":"1.0","type":"link"}
