It measures 1.063 inches inner diameter by 1.25 inches outer diameter with a cross-section thickness of 0.094 inches. The round cross-section design features seamless, uniform FEP-Teflon encapsulation that fully encloses a silicone elastomer core. This construction delivers the chemical and temperature resistance of solid PTFE while retaining the elasticity and recovery properties of silicone. The rated temperature range spans -75 degrees F to 400 degrees F, making it suitable for demanding service environments. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis o-ring is suited for use in fluid and gas sealing applications where exposure to aggressive chemicals, wide temperature swings, or media incompatible with standard nitrile or EPDM elastomers is a concern. Common install scenarios include pump flanges, valve stems, fittings, and chemical-handling connections in both residential and light commercial systems. The Dash 121 designation follows standard AS568 sizing and allows straightforward cross-reference to OEM and aftermarket groove specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFEP-Teflon encapsulation provides chemical resistance equivalent to solid PTFE o-rings\u003c\/li\u003e\n  \u003cli\u003eSilicone elastomer core delivers flexibility and elastic recovery across a wide temperature range\u003c\/li\u003e\n  \u003cli\u003eRated from -75 degrees F to 400 degrees F for use in demanding thermal environments\u003c\/li\u003e\n  \u003cli\u003eSeamless, uniform encapsulation prevents media ingress at the seam\u003c\/li\u003e\n  \u003cli\u003e70 durometer hardness rating suitable for standard groove tolerances\u003c\/li\u003e\n  \u003cli\u003eRound cross-section conforms to AS568 Dash 121 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard AS568 Dash 121 replacement o-ring for use in any groove machined to accept a 1.063-inch ID by 1.25-inch OD by 0.094-inch cross-section seal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. De-energize and depressurize the system fully before removing the existing seal. Inspect the mating groove for burrs, scoring, or contamination before seating the replacement ring. Avoid using petroleum-based lubricants with PTFE-encapsulated seals; consult the system manufacturer for compatible assembly lubricants.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.063 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross-Section Thickness\u003c\/strong\u003e: 0.094 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 121\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 Durometer (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  \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: TES70121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51704124178738,"sku":"TES70121","price":16.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_ac1b16d7-0cb1-45a8-a030-68a91fc2b778.jpg?v=1788420753","url":"https:\/\/voomisupply.com\/products\/value-collection-tes70121-o-ring-dash-121-ptfe-silicone","provider":"Voomi Supply","version":"1.0","type":"link"}
