The ring measures 0.875 inches inside diameter, 1.000 inches outside diameter, and 0.0625 inches thick with a round cross section. Construction consists of a seamless, uniform FEP-Teflon encapsulation that completely encloses a silicone elastomer core. This design delivers the chemical and temperature resistance of solid PTFE while retaining the elasticity and compression recovery of silicone. Licensed tradespeople and maintenance technicians install this ring wherever standard elastomers are incompatible with aggressive media or wide thermal cycling.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in residential and light commercial mechanical systems including water treatment equipment, chemical feed lines, compressed gas fittings, refrigerant service ports, and general plumbing connections requiring a chemically inert seal. The Dash 020 sizing is a common standard dimension found in many OEM and aftermarket fitting configurations. The temperature rating of -75 degrees F to 400 degrees F makes it appropriate for both cryogenic-adjacent and high-heat service environments. It is packaged individually and intended for direct replacement or repair use by qualified tradespeople.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFEP-Teflon encapsulation is seamless and uniform, eliminating weak points at the seam\u003c\/li\u003e\n\u003cli\u003eSilicone elastomer core provides compression recovery and flexibility that solid PTFE cannot match\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -75 degrees F to 400 degrees F suits a wide range of mechanical service conditions\u003c\/li\u003e\n\u003cli\u003eRound cross section ensures consistent gland fill and predictable sealing load\u003c\/li\u003e\n\u003cli\u003eHardness rated at 70 Shore A for a firm, reliable seal under pressure\u003c\/li\u003e\n\u003cli\u003eDash 020 standard sizing for straightforward cross-reference and sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service O-ring for any system or fitting that accepts a Dash 020 size O-ring with a 0.875-inch inside diameter and 1.000-inch outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified mechanic following applicable codes including IPC and IFGC where relevant. De-pressurize and isolate the system completely before removing the old O-ring or installing the new one. Inspect the gland surface for nicks, burrs, or corrosion that could damage the encapsulation layer. Do not use petroleum-based lubricants with PTFE-encapsulated rings; use only a compatible lubricant approved for PTFE or silicone seals.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 020\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PTFE-Encapsulated Silicone (FEP Teflon over Silicone Core)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (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\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\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: TES70020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723584438578,"sku":"TES70020","price":16.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_a7bf2230-7558-47e3-a2e4-dd58550c0215.jpg?v=1788606698","url":"https:\/\/voomisupply.com\/products\/value-collection-tes70020-o-ring-dash-020-ptfe-silicone","provider":"Voomi Supply","version":"1.0","type":"link"}
