It features a round cross-section profile and a Shore A hardness of 70, placing it in the hard hardness rating category. Buna-N is the most widely used o-ring elastomer in trade applications, selected for its excellent resistance to petroleum-based fluids, strong compression set recovery, and solid tear and abrasion resistance. This o-ring ships in a pack of 5.\u003c\/p\u003e\n\u003cp\u003eThis o-ring is suited for static and dynamic sealing applications involving petroleum products, hydraulic fluids, and oils across HVAC, plumbing, and general industrial service. It is appropriate for use in fluid system fittings, valve bodies, pump housings, and pipe connections where a large-diameter face or radial seal is required. The operating temperature range of -40 degrees F to 250 degrees F makes it a reliable choice for a wide range of indoor and outdoor service conditions. It meets SAE and MIL-Spec standards. Note that this part is not FDA approved and should not be used in food-service or potable-water contact applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (NBR) elastomer provides excellent resistance to petroleum products, hydraulic oils, and fuels\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile with 0.25 inches section thickness for consistent seating and sealing\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 (hard rating) for reliable compression set performance\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eStore away from direct sunlight, ozone sources, and electrical equipment that may generate ozone\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service o-ring for Dash 435 groove specifications in petroleum-compatible fluid systems, valves, pumps, and fittings requiring a 5.75 inches ID sealing element.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or fluid system mechanics. Always depressurize and drain the system before removing the existing seal. Lightly lubricate the o-ring with a compatible petroleum-based or synthetic grease before seating it to prevent rolling or tearing during assembly. Inspect the groove for scoring or contamination before installing the new ring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 435\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: 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 Media\u003c\/strong\u003e: Petroleum Products\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: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCH70435\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720885535026,"sku":"ZMSCH70435","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/204d5d87080b826fff03ded5ce3c35a5.jpg?v=1788570492","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70435-o-ring-dash-435-nbr-pack-of-5","provider":"Voomi Supply","version":"1.0","type":"link"}
