It measures 3 inches inside diameter, 3.188 inches outside diameter, and 0.094 inches thick with a round cross section. The 70-durometer hardness rating places it in the hard range, making it well suited for applications that demand dimensional stability under compression. Silicone material gives this ring a wide usable temperature range, from -80 degrees F to 450 degrees F, with good dry heat and ozone resistance. Sold in a pack of 10.\u003c\/p\u003e\u003cp\u003eThis o-ring is used in residential and commercial HVAC equipment, refrigeration piping, plumbing fixtures, chemical handling assemblies, and general industrial sealing where wide temperature range performance is required. The silicone compound offers good weather and ozone resistance and performs reliably in environments with exposure to some chemicals and solvents. Note that oil resistance is limited, so verify fluid compatibility before installation in hydraulic or lubricated systems. Plumbers, HVAC technicians, and maintenance mechanics are the typical installers for this size and type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 151 standard sizing: 3 inches ID, 3.188 inches OD, 0.094 inches thick\u003c\/li\u003e\n\u003cli\u003eSilicone compound rated from -80 degrees F to 450 degrees F\u003c\/li\u003e\n\u003cli\u003e70-durometer hardness for dimensional stability under compression load\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent seating in standard groove profiles\u003c\/li\u003e\n\u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n\u003cli\u003eCompatible with select oils, chemicals, and solvents — verify against specific fluid before use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 151 o-ring replacement for any groove machined to AS568 Dash 151 dimensions in HVAC, plumbing, refrigeration, and general industrial equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eLicensed plumbers and HVAC technicians should depressurize and isolate the system before removing or installing o-rings. Clean the groove and mating surfaces thoroughly before seating the new ring. Avoid stretching the o-ring beyond necessary for installation, as silicone compounds are less elastic than EPDM or Buna-N alternatives. Verify chemical compatibility with the process fluid before final assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 151\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.188 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\u003eHardness\u003c\/strong\u003e: 70 Shore A (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\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: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: ZMSCS70151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721425813810,"sku":"ZMSCS70151","price":15.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65525397009910e86e34cb5ee56ad744.jpg?v=1788577304","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70151-silicone-o-ring-dash-151","provider":"Voomi Supply","version":"1.0","type":"link"}
