It measures 0.734 inches inside diameter, 1.0000 inches outside diameter, and 0.1250 inches in cross-section thickness. The round cross-section profile seats cleanly in standard O-ring grooves. Rated for a hardness of 70 Shore A, this O-ring balances compression set resistance with flexibility across a broad service temperature range of -40 degrees F to 250 degrees F. It carries FDA approval and meets SAE and MIL-Spec standards, making it suitable for both food-grade and general mechanical applications. Each order is fulfilled in a pack of 25.\u003c\/p\u003e\n\u003cp\u003eBuna-N O-rings in the Dash 210 size are standard fare in HVAC refrigerant service fittings, plumbing shutoff valves, hydraulic and pneumatic systems, pool and spa equipment, and fuel-handling assemblies. The Buna-N compound delivers excellent resistance to petroleum-based fluids, oils, and greases encountered in these systems. HVAC technicians, plumbers, and pool service professionals reach for this size when servicing pump seals, valve stems, compression fittings, and flare unions that require a reliable static or low-cycle dynamic seal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (nitrile) compound provides excellent resistance to petroleum products, oils, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eFDA approved white color formulation suitable for food-grade and potable-water-adjacent applications\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating delivers strong compression set resistance and tear and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eRated from -40 degrees F to 250 degrees F for broad service temperature coverage\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards for dimensional and material compliance\u003c\/li\u003e\n  \u003cli\u003eRound cross-section, Dash 210 designation seats in any standard AS568 Dash 210 groove\u003c\/li\u003e\n  \u003cli\u003ePack of 25 units minimizes downtime during multi-unit service calls or scheduled maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for any application calling out an AS568 Dash 210 O-ring in Buna-N.

Shut off fluid supply and depressurize the system fully before removing the existing O-ring. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before seating to prevent rollover and pinching during assembly. Avoid exposing Buna-N seals to ozone-generating equipment or direct sunlight during storage.\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\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 210\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.7340 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross-Section Thickness\u003c\/strong\u003e: 0.1250 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, oils, hydraulic fluids\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: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.818 pounds (package)\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: ZMSCH70FDA210\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700067434802,"sku":"ZMSCH70FDA210","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2f5b75b18772e6c1fc788f76def4c3f.jpg?v=1788385626","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70fda210-o-ring-dash-210-buna-n-fda-25pk","provider":"Voomi Supply","version":"1.0","type":"link"}
