It measures 0.9260 inches inside diameter, 1.0620 inches outside diameter, and 0.0625 inches thick with a round cross section. Hardness is rated at 70 Shore A, placing it in the hard range for reliable compression set performance. The material is FDA approved and rated for use from -40 degrees F to 250 degrees F, making it suitable for a broad range of service conditions involving petroleum-based fluids and lubricants. This O-ring is sold in a package quantity of 25.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is used across HVAC, plumbing, hydraulic, and pneumatic systems wherever a standard Dash 021 face seal or groove seal is required. Buna-N compound delivers excellent resistance to petroleum products, hydraulic oils, and fuels, making it a go-to choice for plumbing technicians, HVAC service professionals, and maintenance mechanics working on fluid handling assemblies. The FDA-approved white compound also suits food-grade and sanitary piping applications where incidental contact with consumables is a concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) compound — the most widely used O-ring elastomer for petroleum product compatibility\u003c\/li\u003e\n  \u003cli\u003eFDA approved white compound suitable for food-grade and sanitary applications\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness for reliable compression set and tear and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 021 standard sizing: 0.9260 inches ID x 1.0620 inches OD x 0.0625 inches thick\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 25 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products, hydraulic oils, fuels, and lubricants.

Shut off system pressure and drain fluid from the line before replacing any O-ring seal. Lightly lubricate the O-ring with a compatible fluid prior to installation to prevent twisting or tearing during seating. Avoid stretching the O-ring beyond what is necessary to seat it in the groove.\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: 021\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.9260 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 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\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\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: 0.234 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: ZMSCH70FDA021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689282339122,"sku":"ZMSCH70FDA021","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/294ae7338bad74ddb1194cdf336090e3.jpg?v=1788256761","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70fda021-buna-n-o-ring-dash-021-fda-pack-25","provider":"Voomi Supply","version":"1.0","type":"link"}
