It measures 5.25 inches inside diameter, 5.625 inches outside diameter, and 0.1875 inches thick, with a round cross section and a Shore A hardness rating of 70. Viton fluoroelastomer construction delivers strong resistance to petroleum-based fluids, high operating temperatures up to 400 degrees F, and low gas permeability, making it a reliable choice for demanding service environments. Licensed tradespeople and maintenance technicians install this ring where chemical compatibility and temperature stability are critical.\u003c\/p\u003e\u003cp\u003eThis O-ring fits applications involving petroleum products, hydraulic fluids, and high-temperature media in residential and commercial systems. Its operating range spans from -15 degrees F to 400 degrees F, covering a wide range of seasonal and process conditions. The low compression set characteristic helps maintain a consistent seal over repeated thermal cycles, reducing the frequency of seal replacement during scheduled maintenance intervals. Sold in a package quantity of two.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) material provides wide-spectrum chemical compatibility with petroleum-based fluids\u003c\/li\u003e\n\u003cli\u003eHigh-temperature resistance rated to 400 degrees F continuous service\u003c\/li\u003e\n\u003cli\u003eLow compression set maintains seal integrity across repeated thermal cycles\u003c\/li\u003e\n\u003cli\u003eLow gas permeability makes this ring suitable for vacuum service applications\u003c\/li\u003e\n\u003cli\u003eRound cross section for standard groove fitment in Dash 355 gland configurations\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness rating classified as hard for positive sealing under pressure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 355 O-ring replacement for any application requiring a 5.25 inches ID fluoroelastomer seal in a round-groove gland.

Shut down and depressurize the system completely before removing the existing seal. Inspect the gland groove for nicks, burrs, or corrosion that could damage the new ring, and apply a compatible lubricant to ease installation without pinching or twisting the O-ring. Avoid using petroleum-incompatible lubricants that may degrade the fluoroelastomer compound.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 355\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\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\u003ePackage Quantity\u003c\/strong\u003e: 2\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: ZMSCV70355\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723980767538,"sku":"ZMSCV70355","price":18.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a48cf6584dd8c6b1574641d7817013ec.jpg?v=1788611016","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70355-viton-o-ring-dash-355","provider":"Voomi Supply","version":"1.0","type":"link"}
