It features a seamless, uniform FEP-Teflon encapsulation that completely encloses a silicone elastomer core, combining the chemical and temperature resistance of solid PTFE with the elasticity and recovery properties of silicone. The round cross-section measures 0.125 inches thick, with an inside diameter of 1.313 inches and an outside diameter of 1.563 inches. It is rated to a hardness of 70 Shore and carries a hard hardness rating. Licensed trades including plumbers, HVAC technicians, and industrial maintenance mechanics install this style of o-ring in fluid and gas handling systems.\u003c\/p\u003e\n\u003cp\u003eThis o-ring is suited for use in high-chemical-exposure environments such as process piping, fluid transfer fittings, valve stems, and pump assemblies in both residential and light commercial systems. The PTFE-encapsulated construction makes it particularly well-suited for sealing against aggressive media that would degrade standard rubber o-rings. It performs reliably across a working temperature range of -75 degrees F to 400 degrees F, making it appropriate for both cryogenic and elevated-temperature service conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSeamless FEP-Teflon encapsulation fully encloses the silicone elastomer core for uniform chemical resistance\u003c\/li\u003e\n  \u003cli\u003eWorking temperature range: -75 degrees F to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross-section with 0.125 inch thickness and Dash 219 sizing\u003c\/li\u003e\n  \u003cli\u003eHardness of 70 Shore (hard rating) for consistent compression and recovery\u003c\/li\u003e\n  \u003cli\u003eMatches chemical resistance of solid PTFE o-rings while retaining elastomer flexibility\u003c\/li\u003e\n  \u003cli\u003eSold individually; minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or retrofit sealing component for Dash 219 o-ring grooves in plumbing, HVAC, industrial fluid transfer, and pump or valve assemblies requiring PTFE-level chemical resistance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified mechanic. Depressurize and isolate the affected system before removing the old o-ring and seating the replacement. Inspect the groove for scoring or corrosion prior to installation and confirm groove dimensions match the Dash 219 specification. Avoid twisting or stretching the o-ring during seating, as distortion can compromise the encapsulation layer and lead to seal failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 219\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: PTFE-Encapsulated Silicone (FEP Teflon over Silicone Elastomer Core)\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: TES70219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697456939314,"sku":"TES70219","price":18.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_1f49cf2a-da3c-4a5e-b092-dac5c5d2a095.jpg?v=1788351852","url":"https:\/\/voomisupply.com\/products\/value-collection-tes70219-o-ring-dash-219-ptfe-silicone","provider":"Voomi Supply","version":"1.0","type":"link"}
