Rated at 70 Shore A hardness, this O-ring carries FDA approval and meets SAE and MIL-Spec standards. The white Buna-N compound delivers excellent resistance to petroleum products along with strong compression set, tear resistance, and abrasion resistance. It is installed by licensed plumbers, HVAC technicians, hydraulic system technicians, and mechanical contractors across a wide range of fluid-sealing applications.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in systems handling petroleum-based fluids, hydraulic oils, fuels, and compatible media. The Buna-N elastomer is the most widely used O-ring material in industrial and HVAC applications due to its broad chemical compatibility and reliable sealing performance across a working temperature range of -40 degrees F to 250 degrees F. The FDA-approved compound makes it appropriate for select food-processing and sanitary equipment applications where incidental contact compliance is required. Supplied in a package quantity of 10.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFDA-approved white Buna-N compound meets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating for reliable sealing under compression\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross section with 0.125-inch thickness for standard groove fitment\u003c\/li\u003e\n  \u003cli\u003eExcellent resistance to petroleum products, hydraulic fluids, and fuels\u003c\/li\u003e\n  \u003cli\u003eGood tear and abrasion resistance with low compression set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products and petroleum-based hydraulic fluids.

Depressurize and isolate the system completely before removing the old O-ring or installing the new one. Lubricate the O-ring with a compatible fluid or approved O-ring lubricant prior to seating to avoid twisting or tearing during assembly. Do not use petroleum-incompatible lubricants with Buna-N seals.\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: 219\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.296 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.562 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 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 Media\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.28 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: ZMSCH70FDA219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697686479154,"sku":"ZMSCH70FDA219","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9538a4a85572d271b8e2cc5237f2369.jpg?v=1788354088","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70fda219-o-ring-dash-219-nbr-70a-fda","provider":"Voomi Supply","version":"1.0","type":"link"}
