Made from white polytetrafluoroethylene (PTFE) resin, it features a round cross section with a 0.926-inch inside diameter, a 1.063-inch outside diameter, and a 0.0625-inch (1\/16 inch) thickness. PTFE material provides chemical inertness, zero water absorption, low friction, and strong dielectric strength — properties that make it suitable for demanding fluid, gas, and chemical system sealing tasks. Licensed trades including plumbers, HVAC technicians, and industrial service professionals install this type of O-ring in valves, fittings, and mechanical assemblies.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for both residential and commercial applications where standard elastomeric seals would fail due to chemical exposure, extreme temperature, or moisture. The Dash 021 sizing standard makes it a direct fit for equipment engineered to that specification. It performs across a broad temperature range, from -300 degrees F to 500 degrees F, covering cryogenic service as well as high-heat process environments. Each package contains 50 O-rings, making it practical for service technicians who stock common seal sizes for field repairs and scheduled maintenance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePTFE construction offers chemical inertness and zero water absorption for harsh fluid and gas environments\u003c\/li\u003e\n\u003cli\u003eRated from -300 degrees F to 500 degrees F for cryogenic through high-temperature service\u003c\/li\u003e\n\u003cli\u003eRound cross section in standard Dash 021 sizing for drop-in replacement compatibility\u003c\/li\u003e\n\u003cli\u003eLow friction surface reduces wear on mating surfaces in valve and fitting assemblies\u003c\/li\u003e\n\u003cli\u003eMedium hardness (55) balances sealing compression with flexibility\u003c\/li\u003e\n\u003cli\u003eSold in a pack of 50 for bench stock and field service replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in valves, fittings, pumps, and mechanical assemblies requiring a Dash 021 PTFE O-ring with a 0.926-inch inside diameter and 1.063-inch outside diameter.

Always depressurize and isolate the system before removing existing seals or installing new ones. Inspect the O-ring groove for damage, debris, or scoring before seating the new ring. PTFE does not require lubricant for installation, but verify compatibility with any lubricant used on mating components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PTFE (Polytetrafluoroethylene)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.926 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.063 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: 021\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: 50\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: ZMSCTFE021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709850714418,"sku":"ZMSCTFE021","price":114.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_db070c70-af86-4681-9431-6990768e4d18.jpg?v=1788461363","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsctfe021-ptfe-o-ring-dash-021-pack-50","provider":"Voomi Supply","version":"1.0","type":"link"}
