It measures 0.924 inches inside diameter, 1.125 inches outside diameter, and 0.0937 inches (3\/32 inches) thick with a round cross section. The seamless Teflon FEP encapsulation completely encloses a silicone elastomer core, delivering the chemical and temperature resistance of solid PTFE combined with the elasticity and recovery of silicone. This O-ring is rated for service from -75 degrees F to 400 degrees F, making it suitable for demanding fluid and gas sealing applications in HVAC, plumbing, and chemical process piping systems. Licensed tradespeople including HVAC technicians, plumbers, and industrial service techs are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is used wherever a standard Dash 119 cross-section seal is required and where exposure to aggressive chemicals, steam, or wide temperature swings would degrade a plain rubber O-ring. Typical applications include valve stems, pump housings, refrigerant fittings, compressed air connections, and chemical-handling lines. The PTFE outer shell resists oils, solvents, fuels, and many acids that attack standard elastomers. The silicone core maintains flexibility at low temperatures where PTFE alone would become too rigid to seal effectively. Sold individually, this part is a direct drop-in replacement for any Dash 119 O-ring position calling for PTFE-encapsulated or FEP-encapsulated construction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePTFE FEP encapsulation provides chemical resistance matching solid PTFE O-rings\u003c\/li\u003e\n  \u003cli\u003eSilicone elastomer core delivers flexibility and elastic recovery from -75 degrees F to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003eSeamless and uniform encapsulation prevents core exposure and seal failure\u003c\/li\u003e\n  \u003cli\u003eRound cross section conforms to standard Dash 119 O-ring groove dimensions\u003c\/li\u003e\n  \u003cli\u003eHard (70 durometer) rating suits moderate-to-high pressure sealing applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct replacement for standard Dash 119 O-ring positions requiring PTFE-encapsulated or FEP-encapsulated silicone construction across HVAC, plumbing, and fluid-handling equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down or depressurize the system completely before replacing any O-ring in a pressurized line or fitting. Clean the groove and mating surfaces to remove debris or remnants of the old seal before seating the new O-ring. Avoid twisting the O-ring during installation, as torsional stress on the encapsulation layer can create leak paths. Follow applicable codes such as IPC or IFGC for plumbing and gas-line sealing requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 119\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.924 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches (3\/32 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 (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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: TES70119\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692779176242,"sku":"TES70119","price":16.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_8a702668-0be4-42bc-b452-9adfb7c00c48.jpg?v=1788302748","url":"https:\/\/voomisupply.com\/products\/value-collection-tes70119-o-ring-dash-119-ptfe-silicone","provider":"Voomi Supply","version":"1.0","type":"link"}
