With a 24-inch inside diameter, a 24.375-inch outside diameter, and a 0.1875-inch (3\/16 inch) cross-section thickness, this round-profile O-ring seals large-bore flanges, pipe joints, vessel covers, and pump housings. Rated for service from -15 degrees F to 400 degrees F, the fluoroelastomer compound delivers low compression set and low gas permeability, making it suitable for demanding industrial and fluid-handling environments.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is well-suited for large-diameter sealing applications in industrial plumbing, HVAC chillers, process piping, hydraulic systems, and petroleum fluid handling. Its 70-durometer hardness (Hard rating) provides firm resistance to extrusion under moderate pressure. The fluoroelastomer material offers wide-spectrum chemical resistance and is particularly effective in contact with petroleum-based fluids, fuels, and high-temperature media. Plumbers, pipefitters, and industrial maintenance technicians typically install this part during flange makeup or equipment overhaul procedures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton-type) compound with good resistance to petroleum products and aggressive chemicals\u003c\/li\u003e\n  \u003cli\u003eWide temperature service range: -15 degrees F to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 durometer (Hard) round cross-section for low compression set and extrusion resistance\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability — suitable for vacuum service and gas-containment applications\u003c\/li\u003e\n  \u003cli\u003eLarge-bore Dash 393 profile: 24-inch ID, 24.375-inch OD, 0.1875-inch cross-section\u003c\/li\u003e\n  \u003cli\u003eBlack color; sold individually (package quantity of 1)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products and a wide spectrum of chemical media as noted by the manufacturer.

Depressurize, de-energize, and fully drain the system before removing the existing O-ring or disassembling any flange or fitting. Inspect the gland and mating surfaces for nicks, corrosion, or contamination before seating the new O-ring. Do not roll or twist the O-ring during installation, and avoid using sharp tools that could nick the sealing surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton-type)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 393\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 24 inches (24.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 24.375 inches (24-3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross-Section Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 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 durometer (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\u003eCompatible Material\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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  \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: ZMSCV70393\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698899550514,"sku":"ZMSCV70393","price":33.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_03961e51-b645-40b4-9d8c-463410484690.jpg?v=1788369596","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70393-viton-o-ring-dash-393","provider":"Voomi Supply","version":"1.0","type":"link"}
