It measures 11 inches inside diameter, 11.375 inches outside diameter, and 0.1875 inches thick with a round cross section. At 70 Shore A hardness, this is a hard-rated O-ring suited for applications that demand dimensional stability under load. Fluoroelastomer construction provides strong resistance to petroleum-based fluids, low compression set, and high-temperature service up to 400 degrees F. Licensed HVAC technicians, plumbers, pipefitters, and industrial maintenance professionals use this style of large-diameter O-ring in sealing flanged connections, pump housings, valves, and fluid-transfer assemblies.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial systems where exposure to petroleum products, hydraulic fluids, or elevated temperatures is a factor. Its wide chemical compatibility and low gas permeability make it a reliable choice for vacuum service applications and systems requiring a consistent, long-lasting seal. The large 11-inch ID places it in applications such as large-bore valve bodies, tank covers, pump flanges, and pressure vessel closures where a precision-dimensioned seal is critical to system integrity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) construction rated for service from -15 degrees F to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness (hard rating) for dimensional stability under compression\u003c\/li\u003e\n  \u003cli\u003eRound cross section, 0.1875 inches thick, for consistent seating in standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003eGood resistance to petroleum products and a wide spectrum of chemical compatibility\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability makes this suitable for vacuum service applications\u003c\/li\u003e\n  \u003cli\u003eLow compression set helps maintain sealing force over extended service intervals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or maintenance seal for large-bore fluid and gas system components requiring a Dash 379 O-ring with fluoroelastomer material and 70 Shore A hardness.

Depressurize and drain the system fully before removing the old O-ring or installing this part. Inspect the mating groove for nicks, scoring, or debris that could compromise the seal. Lightly lubricate the O-ring with a fluid compatible with fluoroelastomer before seating to prevent twisting or tearing during assembly.\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\u003eInside Diameter\u003c\/strong\u003e: 11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 11.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 379\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: 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 Media\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\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCV70379\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696420651314,"sku":"ZMSCV70379","price":19.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45cbe9506772cec0d9151bbecdde323c.jpg?v=1788342475","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70379-viton-o-ring-dash-379","provider":"Voomi Supply","version":"1.0","type":"link"}
