Thermwell R516WH High Density Foam Tape 1-1/4x7/16 in

Product Description

The THERMWELL R516WH is a white, high-density foam tape designed for sealing, cushioning, and vibration dampening across a wide range of residential and light commercial applications. The tape measures 1-1/4 inches wide by 7/16 inches thick and comes in a 10-foot roll. The pressure-sensitive self-stick backing allows for fast, tool-free installation on most clean, dry surfaces. High-density foam construction holds its shape under compression, making it effective as a weather strip, gasket material, or cushioning layer. HVAC technicians, appliance service pros, and maintenance personnel routinely keep rolls on hand for quick field fixes.

This tape is suited for use as a weather strip around doors and windows, a sealing gasket around air conditioner units, and a door gasket on refrigerator and freezer compartments. It also works as a cushioning layer under major appliances to reduce vibration transfer to floors. Automotive and marine maintenance crews use it on cars, trucks, and boats to prevent rattles, vibrations, and squeaks where panels or components contact each other.

Installation Notes

Clean and dry the mounting surface thoroughly before applying the tape to ensure full adhesion. Cut to length with scissors or a utility knife. Press firmly along the full length of the applied strip to activate the adhesive bond. For HVAC or appliance sealing applications, power down the unit before inspecting and replacing any existing gasket or foam seal.
