At 17 mil total thickness, this tape delivers a robust, conformable bond across sheet metal, flexible duct connections, and ductboard surfaces. It carries a tensile strength of 25 lbs\/in and performs across a temperature range of -20 degrees F to 200 degrees F, making it suitable for both supply and return-side applications in a wide range of climates. HVAC installers and sheet metal mechanics reach for this tape when the job demands a UL 723-tested, SMACNA-compliant seal.\u003c\/p\u003e\n\u003cp\u003eThe SF 685 foil tape is used on low-, medium-, and high-pressure duct systems in commercial mechanical rooms, residential forced-air installations, and light industrial HVAC applications. It meets Pressure Classes SMACNA 1\/2, 1, 2, 3, 4, and 6 and Seal Classes A, B, and C, covering virtually every duct pressure and leakage classification encountered in standard sheet metal work. Each roll is 2 inches wide and 100 feet long. The tape ships 24 rolls per case, making it practical for stocking a service van or a sheet metal fabrication shop.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e17 mil total thickness for a durable, puncture-resistant seal on duct joints and seams\u003c\/li\u003e\n  \u003cli\u003eTensile strength of 25 lbs\/in resists tearing during installation and system pressurization\u003c\/li\u003e\n  \u003cli\u003e560 percent elongation allows the tape to conform to irregular surfaces and curved duct transitions\u003c\/li\u003e\n  \u003cli\u003eRated from -20 degrees F to 200 degrees F for cold-climate and high-temperature supply-air applications\u003c\/li\u003e\n  \u003cli\u003eMeets FSI 20\/SDI 40 flame spread and smoke development requirements\u003c\/li\u003e\n  \u003cli\u003eTested in accordance with UL 723 for use in air-handling systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sealing solution for sheet metal, flex duct, and ductboard assemblies in SMACNA-rated commercial and residential HVAC duct systems meeting Pressure Classes 1\/2 through 6 and Seal Classes A, B, and C.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLicensed sheet metal mechanics and HVAC technicians should apply this tape to clean, dry, and dust-free surfaces for maximum adhesion. Power down air-handling equipment before sealing active duct joints to prevent pressurization during application. Follow local mechanical codes and SMACNA installation standards for required overlap and coverage at joints. Do not apply over wet mastic or compromised duct liner without cleaning and priming the substrate first.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SF 685\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 100 ft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Thickness\u003c\/strong\u003e: 17 mil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTensile Strength\u003c\/strong\u003e: 25 lbs\/in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElongation\u003c\/strong\u003e: 560%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 200 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -20 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards Met\u003c\/strong\u003e: FSI 20\/SDI 40; Pressure Classes SMACNA 1\/2, 1, 2, 3, 4 and 6; Seal Classes A, B, C; Tested in accordance with UL 723\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 24 rolls per case\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: SHURTAPE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SHUR-200664\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SHURTAPE","offers":[{"title":"Default Title","offer_id":51383780835634,"sku":"SHUR-200664","price":43.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670127.jpg?v=1782607267","url":"https:\/\/voomisupply.com\/products\/shurtape-shur-200664-shurmastic-sf-685-foil-tape-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
