The encapsulation consists of a seamless, uniform FEP-PTFE outer shell that completely encloses a silicone elastomer core. This construction delivers the chemical and temperature resistance of solid PTFE while retaining the elasticity and compression recovery of a conventional elastomer O-ring. The ring measures 2.5 inches inside diameter, 2.75 inches outside diameter, and 0.125 inches in cross-section thickness, with a round cross-section profile and a hardness rating of 70 Shore. It is installed by plumbers, pipefitters, HVAC technicians, and industrial mechanics.\u003c\/p\u003e\n\u003cp\u003eThis O-ring suits static and low-dynamic sealing applications where aggressive media, steam, solvents, or wide thermal cycling would degrade standard nitrile or EPDM seals. Typical installations include flanged connections, valve seats, pump housings, and process fluid fittings in commercial, industrial, and mechanical systems. The Dash 230 designation corresponds to a standardized AS568 cross-section and diameter combination, making it a direct dimensional fit wherever that dash number is specified in engineering drawings or maintenance documentation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSeamless FEP-PTFE encapsulation fully encloses the silicone core for uniform chemical resistance\u003c\/li\u003e\n  \u003cli\u003eRated from -75 degrees F to 400 degrees F continuous service temperature\u003c\/li\u003e\n  \u003cli\u003eRound cross-section with 0.125-inch thickness and Dash 230 dimensional designation\u003c\/li\u003e\n  \u003cli\u003eMatches chemical resistance of solid PTFE O-rings while offering elastomeric recovery\u003c\/li\u003e\n  \u003cli\u003eHardness rated Hard (70 Shore) for firm, reliable groove seating\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit with a 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 maintenance-stock O-ring for any application specifying a Dash 230 O-ring with a 2.5-inch inside diameter, 2.75-inch outside diameter, and 0.125-inch cross-section thickness per AS568 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down or isolate the system and relieve all pressure before removing the old seal or installing the replacement. Inspect the groove for scoring, corrosion, or dimensional damage before seating the new ring. Because PTFE encapsulation is less forgiving of sharp edges than solid elastomers, ensure the groove edges and mating surfaces are deburred and clean. Installation typically requires no special tooling beyond a clean, lint-free installation surface and appropriate thread or flange torque procedures per the equipment manufacturer's specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.75 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: 230\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\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\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: TES70230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51704357093682,"sku":"TES70230","price":20.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_968bc655-6fe2-4446-a9be-6ccae5f286c7.jpg?v=1788422224","url":"https:\/\/voomisupply.com\/products\/value-collection-tes70230-o-ring-dash-230-ptfe-silicone","provider":"Voomi Supply","version":"1.0","type":"link"}
