The CARLISLE HARDCAST 327981 is a cover tape designed for sealing and protecting duct joints, seams, and connections in HVAC ductwork systems. Supplied in a 6-inch-wide by 100-foot roll, this tape provides broad coverage per application, reducing the number of passes needed to seal wide seam areas. At 31 pounds per roll, it carries the mass expected of a heavy-duty foil or reinforced tape product. HVAC sheet metal installers and duct fabricators typically apply this tape as part of a complete duct sealing system in both new construction and retrofit applications.
This tape is suited for use in commercial and residential HVAC duct fabrication and installation where code-compliant sealing of joints, longitudinal seams, and fittings is required. The 6-inch width makes it particularly useful for covering wide butt joints and factory-applied mastic seams on rigid ductboard or metal duct assemblies. It is intended for use by licensed HVAC contractors and sheet metal mechanics working on low-pressure air distribution systems.
Designed as an OEM-style cover tape for use in residential and commercial HVAC duct sealing systems where a wide-format tape is required at seams and joints.
Installation should be performed by a licensed HVAC technician or sheet metal mechanic in accordance with SMACNA standards and local mechanical codes. Shut down and de-energize the air handling system before working on duct assemblies. Ensure all mating surfaces are clean, dry, and free of dust or oil before tape application for proper adhesion. Do not apply this tape as a primary structural connection or as a substitute for mechanical fasteners where required by code.
