It measures 1.688 inches inside diameter, 1.875 inches outside diameter, and 0.094 inches thick. The silicone compound carries a Shore A hardness of 70 and is rated for service from -80 degrees F to 450 degrees F, making it well suited for applications that require wide thermal range performance and dry heat resistance. Each package contains 25 rings. This O-ring is installed by licensed HVAC technicians, plumbers, and mechanical service professionals.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for sealing duties in residential and light commercial HVAC equipment, plumbing connections, and chemical or solvent-handling assemblies where silicone elastomer is compatible with the process media. The silicone material provides good weather and ozone resistance, making it a practical choice for outdoor or exposed service environments. It is not recommended for continuous immersion in oils or petroleum-based fluids, where alternative elastomers such as Buna-N or Viton would be more suitable. The round cross section seats into standard Dash 131 gland geometries without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDash 131 standard sizing: 1.688 inches ID x 1.875 inches OD x 0.094 inches thick\u003c\/li\u003e\n  \u003cli\u003eSilicone compound rated -80 degrees F to 450 degrees F for wide thermal range service\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 for consistent sealing load and compression set resistance\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, chemicals, and solvents in limited-exposure applications\u003c\/li\u003e\n  \u003cli\u003eRound cross section seats in standard Dash 131 gland geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 131 O-ring replacement for any gland machined to AS568 Dash 131 dimensions in HVAC, plumbing, and fluid-handling equipment.

Inspect the gland groove for burrs or corrosion that could damage the new ring during assembly. Lightly lubricating the O-ring with a compatible grease or silicone lubricant eases installation and reduces the risk of tearing. Follow applicable mechanical and plumbing codes for pressure-rated joint reassembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 131\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.688 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.094 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShore A Hardness\u003c\/strong\u003e: 70 (Hard)\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\u003eColor\u003c\/strong\u003e: White\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: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: ZMSCS70131\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694173585714,"sku":"ZMSCS70131","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08e2e05aa79c09a5475ea69d6addc342.jpg?v=1788321271","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70131-silicone-o-ring-dash-131-25pk","provider":"Voomi Supply","version":"1.0","type":"link"}
