This design combines the broad chemical resistance of solid PTFE with the compression recovery and elasticity of a Viton rubber core. The O-ring measures 1.875 inches inside diameter, 2.25 inches outside diameter, and 0.1875 inches thick, with a round cross section. It is rated for service from -75 degrees F to 400 degrees F and carries a hardness rating of 80 Shore. Plumbers, industrial pipefitters, and HVAC technicians use this O-ring in fluid handling and sealing applications where aggressive chemicals or elevated temperatures would degrade standard rubber seals.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial plumbing, HVAC refrigerant system components, chemical transfer lines, and fluid control valve assemblies where a Dash 328 cross-section seal is required. The seamless, uniform FEP encapsulation completely encloses the core elastomer, making it appropriate for applications where metal or equipment surfaces contact chemically active media. It is sold individually and is a direct drop-in for any Dash 328 standard-dimension O-ring groove.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSeamless PTFE FEP encapsulation fully encloses the Viton or silicone elastomer core for uniform chemical resistance\u003c\/li\u003e\n  \u003cli\u003eRated from -75 degrees F to 400 degrees F for wide thermal service range\u003c\/li\u003e\n  \u003cli\u003eRound cross section at 0.1875 inches thickness fits standard Dash 328 O-ring grooves\u003c\/li\u003e\n  \u003cli\u003e80 Shore hardness rating for reliable compression and recovery under load\u003c\/li\u003e\n  \u003cli\u003eMatches chemical and temperature resistance of solid PTFE while retaining elastomeric recovery properties\u003c\/li\u003e\n  \u003cli\u003eBlack color; sold as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or service O-ring for any application requiring a Dash 328 standard O-ring with 1.875 inches inside diameter and 2.25 inches outside diameter in PTFE-encapsulated Viton construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Depressurize and isolate the system fully before removing the old O-ring and installing the replacement. Inspect the mating groove and sealing surfaces for nicks, corrosion, or debris before seating the new O-ring. Avoid using petroleum-based lubricants on PTFE-encapsulated O-rings unless confirmed compatible with both the encapsulant and the system media.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.25 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: 328\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 FEP-Encapsulated Viton (or Silicone) Elastomer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 80 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\u003eFDA Approved\u003c\/strong\u003e: No\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: TEV80328\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699561201970,"sku":"TEV80328","price":24.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e04bcf3e1868e5d6e0afdf16cb6f3c7.jpg?v=1788377475","url":"https:\/\/voomisupply.com\/products\/value-collection-tev80328-o-ring-dash-328-ptfe-viton","provider":"Voomi Supply","version":"1.0","type":"link"}
