The ring features a 1.75-inch inside diameter, a 2.125-inch outside diameter, and a 0.1875-inch cross-section thickness. A seamless FEP (fluorinated ethylene propylene) Teflon shell completely encapsulates a silicone elastomer core, combining the broad chemical resistance of solid PTFE with the compression recovery and elasticity of silicone. It is installed by plumbers, HVAC technicians, and industrial maintenance trades where aggressive media or wide temperature swings rule out standard nitrile or EPDM seals.\u003c\/p\u003e\n\u003cp\u003eThis O-ring suits static and low-dynamic sealing applications across plumbing, HVAC, chemical processing, and food-grade equipment where PTFE-level chemical compatibility is required but a solid PTFE ring lacks adequate elasticity. The round cross-section geometry fits standard Dash 327 gland dimensions. The operating temperature range spans -75 degrees F to 400 degrees F, making it appropriate for both cryogenic-adjacent and high-heat service conditions. It is sold and packaged as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSeamless FEP Teflon encapsulation completely encloses the silicone core with no seams or gaps\u003c\/li\u003e\n  \u003cli\u003eOperating range of -75 degrees F to 400 degrees F suits wide-temperature service environments\u003c\/li\u003e\n  \u003cli\u003eCombines PTFE chemical resistance with silicone elasticity and compression recovery\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile fits standard Dash 327 gland dimensions\u003c\/li\u003e\n  \u003cli\u003eShore hardness rated Hard (70) for firm sealing under compression\u003c\/li\u003e\n  \u003cli\u003eBlack color aids visual inspection during installation and maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or maintenance seal for any application requiring a Dash 327 O-ring gland where PTFE-encapsulated silicone material is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down or depressurize the system fully before replacing any O-ring seal. Inspect the gland groove for nicks, burrs, or corrosion that could compromise the seal before seating the ring. Avoid using sharp tools that could cut or score the FEP encapsulation layer during installation. Follow applicable plumbing or mechanical codes, such as IPC or ASME B31, for pressure-rated assembly requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PTFE-Encapsulated Silicone (FEP shell over silicone core)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 327\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.75 inches (1-3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.125 inches (2-1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\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  \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: TES70327\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692936298802,"sku":"TES70327","price":21.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/31a3d55d90ce579449f3b68d0226ecbf.jpg?v=1788305185","url":"https:\/\/voomisupply.com\/products\/value-collection-tes70327-o-ring-dash-327-ptfe-silicone","provider":"Voomi Supply","version":"1.0","type":"link"}
