This O-ring features a rectangular cross section measuring 0.898 inches inner diameter, 1.000 inch outer diameter, and 0.047 inches thick. With a durometer hardness of 55 (medium) and a working temperature range of -65 to 500 degrees F, it holds up in high-heat and chemically aggressive environments where standard rubber O-rings degrade. Each package contains 25 pieces. HVAC technicians, plumbers, and industrial maintenance professionals use PTFE seals where chemical resistance and wide thermal tolerance are required.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for use in fluid handling, refrigeration, chemical process lines, and pneumatic or hydraulic fittings that demand broad chemical compatibility. The PTFE material resists most acids, solvents, and caustic media. Typical installation scenarios include sealing pipe fittings, valve stems, and mechanical connections in both residential and light commercial systems. The rectangular cross section provides consistent seating in grooves machined to Dash 020 standard dimensions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePTFE material provides excellent chemical resistance across a broad range of acids, solvents, and refrigerants\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -65 to 500 degrees F suits both cryogenic and high-heat service\u003c\/li\u003e\n  \u003cli\u003eDash 020 standard sizing: 0.898 inches ID, 1.000 inch OD, 0.047 inches thick\u003c\/li\u003e\n  \u003cli\u003eRectangular cross section for stable groove seating\u003c\/li\u003e\n  \u003cli\u003eMedium durometer hardness rating of 55 for reliable compression sealing\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-piece package for service inventory or repeat maintenance tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 020 replacement O-ring for any fitting or component machined to Dash 020 groove dimensions requiring a PTFE seal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or mechanical maintenance professionals. Depressurize and isolate the line or fitting before removing the old O-ring and installing the replacement. Ensure the groove is clean and free of debris before seating the new O-ring. Do not stretch or nick the O-ring during installation, as PTFE is less elastic than rubber and will not recover from deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 020\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.898 inches (22.81 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.000 inch (25.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.047 inches (1.19 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness (Durometer)\u003c\/strong\u003e: 55\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -65 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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: ZMSCTST020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699215466802,"sku":"ZMSCTST020","price":17.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd6f8f5a299ed103c9e32a521ecbcd5d.jpg?v=1788373644","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsctst020-ptfe-o-ring-dash-020-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
