It measures 2.25 inches inside diameter, 2.5 inches outside diameter, and 0.125 inches thick, conforming to Dash 228 sizing. PTFE construction provides chemical inertness, low friction, and a rated working range of -300 degrees F to 500 degrees F. Licensed plumbers, HVAC technicians, and industrial service professionals install this type of seal in high-purity, high-temperature, or chemically aggressive fluid systems where elastomeric O-rings would degrade.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in residential and commercial plumbing, HVAC refrigerant circuits, chemical process lines, and fluid handling equipment where PTFE's unique combination of heat resistance, weatherability, zero water absorption, and dielectric strength is required. Its medium hardness rating makes it appropriate for static face-seal and fitting applications. Each package contains 10 O-rings, and the minimum order quantity is 1 package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePTFE material offers broad chemical inertness for aggressive fluid compatibility\u003c\/li\u003e\n\u003cli\u003eOperating range of -300 degrees F to 500 degrees F suits extreme-temperature service\u003c\/li\u003e\n\u003cli\u003eDash 228 standard sizing for straightforward cross-referencing and replacement\u003c\/li\u003e\n\u003cli\u003eRound cross section and medium hardness (55) for reliable static sealing\u003c\/li\u003e\n\u003cli\u003eLow friction and zero water absorption reduce seal degradation over time\u003c\/li\u003e\n\u003cli\u003eSold in packs of 10 for stocking efficiency on multi-unit service calls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 228 PTFE O-ring replacement suitable for static sealing applications in plumbing, HVAC, and chemical fluid systems that require PTFE material compatibility.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified plumber, HVAC technician, or industrial mechanic familiar with O-ring face-seal and fitting applications. Depressurize and isolate the system before disassembling any fitting or valve housing. Inspect the seating surface for nicks or corrosion before installing the new O-ring, as surface defects will cause seal failure. PTFE O-rings should not be stretched excessively during installation; confirm correct dash sizing before proceeding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 228\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PTFE (Polytetrafluoroethylene)\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: 55 (Medium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -300 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 500 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: 10\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: ZMSCTFE228\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":67912003879218,"sku":"ZMSCTFE228","price":43.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_a94b7d32-4720-4649-994e-5cb82d3b682c.jpg?v=1791224841","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsctfe228-ptfe-o-ring-dash-228","provider":"Voomi Supply","version":"1.0","type":"link"}
