Measuring 3 inches wide by 100 feet per roll, it delivers a permanent, waterproof bond to duct substrates without requiring heat activation. The foil backing stays supple after application, conforming to irregular surfaces and maintaining adhesion across temperature cycles. HVAC technicians and sheet metal workers reach for this tape when a durable, code-appropriate mastic-style seal is needed on supply and return duct systems. It contains no asbestos, CFCs, or PCBs, making it compliant with current indoor air quality standards.\u003c\/p\u003e\n\u003cp\u003eThe sf685-3spt is suited for residential and light commercial HVAC duct sealing where sheet metal joints, seams, and connections require a weatherproof, long-lasting seal. The tape is approved for use on both sheet metal and PVC-coated duct assemblies, making it versatile across common duct construction types. It is paintable using paint formulated for aluminum surfaces, which supports finished installations in exposed mechanical spaces. The 100-foot roll length reduces the need for frequent roll changes during larger duct-sealing runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButyl foil construction provides a waterproof, permanent bond to duct substrates\u003c\/li\u003e\n  \u003cli\u003eStays supple after application, conforming to irregular duct surfaces and seams\u003c\/li\u003e\n  \u003cli\u003eSuitable for both indoor and outdoor duct sealing environments\u003c\/li\u003e\n  \u003cli\u003ePaintable with aluminum-compatible paint for finished mechanical installations\u003c\/li\u003e\n  \u003cli\u003eContains no asbestos, CFCs, or PCBs\u003c\/li\u003e\n  \u003cli\u003e3 inches wide by 100 feet per roll for efficient coverage on larger jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on sheet metal ductwork and PVC-coated duct assemblies in residential and commercial HVAC systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or sheet metal workers. Before applying, clean and dry the duct surface to remove dust, oil, and loose debris for maximum adhesion. Power down the air handling system before working on pressurized duct sections.
