The ring measures 2.5 inches inside diameter, 2.875 inches outside diameter, and 0.1875 inches thick with a round cross section. It features a seamless, uniform FEP (fluorinated ethylene propylene) Teflon encapsulation that fully encloses a silicone or Viton elastomer core. This construction delivers the chemical and temperature resistance of solid PTFE while retaining the compression set recovery and flexibility of an elastomeric core. Licensed plumbers, pipefitters, and mechanical contractors install this type of o-ring in process piping, valve assemblies, and pump connections.\u003c\/p\u003e\n\u003cp\u003eThis o-ring is suited for demanding plumbing, HVAC, and industrial process applications where standard rubber seals fail due to chemical exposure or temperature extremes. The Dash 333 designation indicates a standardized size used across a wide range of fittings and flanged connections in both residential and commercial mechanical systems. Its rated operating range of -75 degrees F to 400 degrees F makes it appropriate for hot water, steam-adjacent, and cryogenic service depending on system design. Installers working with aggressive media such as acids, solvents, or caustics will find the PTFE outer layer provides a first line of chemical defense.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSeamless FEP Teflon encapsulation fully encloses silicone or Viton elastomer core for dual-material performance\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -75 degrees F to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross section with 0.1875-inch thickness for consistent seating in standard o-ring grooves\u003c\/li\u003e\n  \u003cli\u003eHard (70 durometer) hardness rating for positive sealing under compression\u003c\/li\u003e\n  \u003cli\u003eDash 333 standardized sizing for straightforward cross-reference and replacement\u003c\/li\u003e\n  \u003cli\u003eMatches chemical resistance of solid PTFE o-rings while retaining elastomeric recovery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 333 o-ring replacement for use in valve bodies, pump housings, flanged fittings, and mechanical connections requiring a 2.5-inch ID seal in plumbing, HVAC, and light industrial piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified mechanical technician. Depressurize and isolate the system fully before removing the existing seal to prevent injury and contamination. Inspect the o-ring groove for damage, debris, or corrosion before seating the new ring; a damaged groove will prevent proper sealing regardless of o-ring quality. Do not use petroleum-based lubricants with PTFE-encapsulated o-rings — use only compatible, media-appropriate lubricants if needed during installation.\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: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 333\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 or Viton 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 (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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: TES70333\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700884439346,"sku":"TES70333","price":20.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_dd8d4df5-f2ca-4e63-83da-5e1929acfdf5.jpg?v=1788395379","url":"https:\/\/voomisupply.com\/products\/value-collection-tes70333-o-ring-dash-333-ptfe-silicone","provider":"Voomi Supply","version":"1.0","type":"link"}
