Thermwell R516H High Density Foam Weatherstrip Tape

Product Description

The THERMWELL R516H is a high-density black foam weatherstrip tape designed to seal gaps and reduce air infiltration around windows, doors, and HVAC equipment. The self-adhesive backing allows for fast, tool-free installation on most clean, dry surfaces. Each roll measures 1.25 inches wide by 0.4375 inches thick by 10 feet long and compresses to fill irregular gaps without cracking or losing its seal. HVAC service technicians, appliance installers, and general contractors reach for this tape when a durable, compressible foam seal is needed on the job site or in the field.

The R516H is suited for residential and light commercial applications. Common uses include sealing the perimeter of window-mounted air conditioners, replacing or supplementing refrigerator and freezer door gaskets, and reducing air leaks around door and window frames. The foam construction also absorbs minor vibrations and prevents rattles on automotive applications including cars and trucks. It ships in a poly bag and is sold as an individual roll, with a package quantity of 12 rolls per case available through Voomi Supply.
