The ring features a round cross-section with a 13\/16-inch inner diameter, a 15\/16-inch outer diameter, and a 1\/16-inch wall thickness. A seamless, uniform FEP-Teflon encapsulation fully encloses a silicone elastomer core. This construction combines the chemical and temperature resistance of solid PTFE with the elasticity and compression recovery of silicone. Licensed HVAC technicians, plumbers, and mechanical trades use o-rings of this type for static and low-motion sealing on fittings, valves, and equipment ports.\u003c\/p\u003e\u003cp\u003eThis o-ring is suited for applications requiring broad chemical compatibility and a wide service temperature range of -75 degrees F to 400 degrees F. The encapsulated design makes it appropriate for use with aggressive media that would degrade a standard silicone or EPDM ring. It is commonly installed in HVAC refrigerant circuits, plumbing valve assemblies, chemical handling equipment, and food-processing or pharmaceutical-adjacent piping where resistance to corrosive fluids is essential but solid PTFE lacks sufficient elasticity for a reliable static seal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePTFE-FEP encapsulation provides full chemical resistance of solid PTFE while retaining core elastomer recovery\u003c\/li\u003e\n\u003cli\u003eWide temperature range: -75 degrees F to 400 degrees F\u003c\/li\u003e\n\u003cli\u003eRound cross-section for consistent compression and sealing contact\u003c\/li\u003e\n\u003cli\u003eHard durometer rating (70 Shore) for resistance to extrusion under pressure\u003c\/li\u003e\n\u003cli\u003eSeamless, uniform encapsulation prevents pinhole leaks or delamination at the seam\u003c\/li\u003e\n\u003cli\u003eDash 019 sizing for straightforward replacement and cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement o-ring for any application specifying a Dash 019 PTFE-encapsulated silicone ring with a 13\/16-inch inner diameter, 15\/16-inch outer diameter, and 1\/16-inch thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified trade professional with the system fully depressurized and isolated before removing the old seal. Inspect the o-ring groove for nicks, burrs, or corrosion before seating the new ring. Do not use petroleum-based lubricants on PTFE-encapsulated rings; use only a compatible fluid or PTFE-safe lubricant if assembly requires it. Follow applicable codes such as the IPC or IFGC for piping system pressure testing after seal replacement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PTFE-FEP Encapsulated Silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 019\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter (Decimal)\u003c\/strong\u003e: 0.9380 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches (1\/16 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 (Hard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -75 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\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\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\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: TES70019\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720528068914,"sku":"TES70019","price":15.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_ab6939ab-3767-45c2-98ea-d148913acede.jpg?v=1788565581","url":"https:\/\/voomisupply.com\/products\/value-collection-tes70019-ptfe-silicone-o-ring-dash-019","provider":"Voomi Supply","version":"1.0","type":"link"}
