The THERMWELL R534WH is a self-adhesive, high-density white foam weatherstrip tape designed to seal gaps and reduce air infiltration around windows, doors, and HVAC equipment. Measuring 0.75 inches wide by 0.3125 inches thick with a 10-foot length per roll, this tape compresses to conform to irregular gaps and uneven surfaces. The pressure-sensitive adhesive backing allows for fast, tool-free installation on clean, dry surfaces. HVAC technicians and appliance service pros reach for this tape when a fast, compressible seal is needed between a unit and its surrounding frame or cabinet opening.
This tape is suited for residential and light commercial applications. Common uses include sealing the perimeter of window air conditioner units to prevent unconditioned air bypass, replacing or supplementing refrigerator and freezer door gaskets, and blocking drafts around door and window frames. It also serves as a vibration-dampening buffer on automotive components including cars and trucks where rattles and squeaks occur at panel joints. The self-stick backing eliminates the need for separate adhesives on most standard surfaces.
Designed for use as a compressible gap seal on residential windows, doors, window air conditioner units, refrigerator and freezer door frames, and automotive panel joints where a self-adhesive foam tape is appropriate.
Clean and dry all surfaces thoroughly before applying the tape to ensure proper adhesion. Power down or unplug any appliance before applying tape around compressor or door gasket areas. Cut to length with scissors or a utility knife. Press firmly along the full length of the tape run to activate the adhesive bond.
