At 3 inches wide and 50 feet long with a 30 mil thickness, this gray foil-backed tape delivers a durable, conformable bond over sheet metal, flexible duct, and rigid duct board surfaces. HVAC technicians and sheet metal contractors reach for this tape when a reliable, long-lasting air seal is required at supply and return duct connections, plenums, and duct penetrations through walls or mechanical chases.\u003c\/p\u003e\n\u003cp\u003eThis tape is suited for residential and light commercial HVAC ductwork where both indoor and outdoor exposure is a factor. Typical install scenarios include sealing duct joints in attic spaces, crawlspaces, rooftop unit connections, and exterior mechanical enclosures. The aluminum foil facing resists moisture, UV, and temperature cycling, making it appropriate for unconditioned spaces where plain cloth or poly tapes would break down over time. It is commonly applied by HVAC installers and sheet metal mechanics during new construction and retrofit duct sealing work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e30 mil total thickness for a robust, conformable seal over irregular duct surfaces\u003c\/li\u003e\n  \u003cli\u003e3 inches wide by 50 foot roll length for efficient coverage on standard duct flanges and seams\u003c\/li\u003e\n  \u003cli\u003eAluminum foil facing resists moisture, UV exposure, and temperature extremes\u003c\/li\u003e\n  \u003cli\u003eGray finish blends with standard galvanized sheet metal ductwork\u003c\/li\u003e\n  \u003cli\u003eSuitable for both indoor and outdoor HVAC duct sealing applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use foil mastic tape for residential and light commercial HVAC ductwork sealing applications on sheet metal, flexible duct, and rigid duct board systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLicensed HVAC technicians and sheet metal mechanics typically install this tape as part of duct sealing work governed by local mechanical codes and ASHRAE standards. Clean and dry all surfaces before application to ensure full adhesive contact. Do not stretch the tape during application, as this can reduce edge adhesion and lead to lifting over time. Follow all applicable local mechanical and energy codes regarding duct sealing requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 30 mil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication Type\u003c\/strong\u003e: Indoor and Outdoor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31201500\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: COATING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: tape-aft701-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COATING","offers":[{"title":"Default Title","offer_id":51138512159026,"sku":"TAPE-AFT701-3","price":59.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532042.png?v=1778258092","url":"https:\/\/voomisupply.com\/products\/coating-tape-aft701-3-aluminum-foil-mastic-tape-3-in-x-50-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
