It measures 17 inches inside diameter by 17.25 inches outside diameter with a cross-sectional thickness of 0.125 inches and a round cross-section profile. The compound is rated at 70 Shore A hardness, which falls in the hard range, and carries a working temperature range of -15 degrees F to 400 degrees F. HVAC, plumbing, and industrial maintenance technicians use this O-ring as a replacement seal in large-diameter flanged assemblies, pump housings, and fluid system couplings.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for sealing applications involving petroleum-based fluids, hydraulic oils, fuels, and many industrial chemicals. Its low compression set characteristic helps it maintain a reliable seal under sustained clamping loads. The low gas permeability rating also makes it a practical choice for vacuum service applications. Typical installation scenarios include large-bore pipe flanges, heat exchanger covers, pump volute joints, and industrial valve bonnets found in commercial mechanical systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) compound provides good resistance to petroleum products and a wide spectrum of industrial chemicals\u003c\/li\u003e\n  \u003cli\u003eWorking temperature range of -15 degrees F to 400 degrees F suits high-heat service environments\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness (hard rating) resists extrusion under pressure\u003c\/li\u003e\n  \u003cli\u003eLow compression set helps maintain sealing force over extended service life\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability makes this O-ring suitable for vacuum service applications\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile conforms to standard O-ring groove dimensions for Dash 283\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or MRO seal for large-diameter assemblies requiring a Dash 283 O-ring groove.

De-pressurize and drain the system before removing any existing seals or opening flanged joints. Lubricate the O-ring with a compatible fluid or grease before seating it in the groove to prevent tearing during assembly. Avoid twisting or spiraling the O-ring during installation, as this can compromise the sealing surface and reduce service life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 283\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 17.25 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: -15 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 400 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Petroleum products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ZMSCV70283\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691876614450,"sku":"ZMSCV70283","price":18.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_7ad25563-c8d1-448e-b5f0-53016a76ba7b.jpg?v=1788290687","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70283-viton-o-ring-dash-283","provider":"Voomi Supply","version":"1.0","type":"link"}
