With a 5.5-inch inside diameter, 6-inch outside diameter, and 0.25-inch thickness, this round cross-section ring seals large-bore connections in plumbing, HVAC, chemical processing, and industrial equipment. The silicone compound carries a Shore A hardness of 70, providing a firm yet compressible seal. Each order includes a pack of 5 rings. Licensed plumbers, pipefitters, and maintenance technicians are the primary installers of this size class of O-ring.\u003c\/p\u003e\u003cp\u003eThis O-ring suits applications where components are exposed to elevated heat, dry heat cycles, weather, or ozone. The silicone material performs from -80 degrees F to 450 degrees F, making it appropriate for high-temperature plumbing flanges, HVAC ductwork connections, large-diameter valve bodies, and similar trade installations. It also offers limited resistance to oils, chemicals, and solvents. It is not FDA approved and should not be specified for food-contact or pharmaceutical applications without independent verification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 433 standard sizing: 5.5 inches ID, 6 inches OD, 0.25 inches thick\u003c\/li\u003e\n\u003cli\u003eSilicone compound rated from -80 degrees F to 450 degrees F continuous service\u003c\/li\u003e\n\u003cli\u003eShore A 70 hardness — firm, hard rating for positive compression sealing\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent groove fit and uniform seal load\u003c\/li\u003e\n\u003cli\u003eGood resistance to weather and ozone degradation\u003c\/li\u003e\n\u003cli\u003eSold in a pack of 5 rings per order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 433 O-ring replacement suitable for large-bore grooves requiring a 5.5-inch ID silicone seal in plumbing, HVAC, and industrial equipment applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified maintenance technician. Depressurize and de-energize the system and drain all fluid from the affected line before removing the old O-ring. Inspect the groove for burrs, corrosion, or damage before seating the new ring. Do not use petroleum-based lubricants on silicone O-rings; use a silicone-compatible lubricant only.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (Hard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 433\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -80 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 450 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Oils, Chemicals, Solvents (limited oil resistance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 rings\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: ZMSCS70433\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696845816114,"sku":"ZMSCS70433","price":22.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f8a515263c8181537d03b8f0203c376.jpg?v=1788346957","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70433-silicone-o-ring-dash-433-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
