Thermwell R930H Black Foam Weatherstrip Tape 1/2x9/16

Product Description

The THERMWELL R930H is a high-density, self-adhesive black foam weatherstrip tape designed to seal gaps and reduce air infiltration around windows, doors, and HVAC equipment. Measuring 0.5 inches wide by 0.5625 inches thick and 10 feet in length, it compresses to conform to irregular surfaces and uneven gaps. The closed-cell foam construction maintains a consistent seal under compression without taking a permanent set under normal service conditions. HVAC technicians, appliance service pros, and general contractors reach for this tape when a fast, peel-and-stick seal is required during service or installation calls.

This weatherstrip tape is suited for both residential and light commercial applications. It seals the perimeter of window-unit air conditioners, acts as a replacement door gasket on refrigerators and freezers, and fills gaps around windows and doors to reduce drafts and energy loss. The self-stick backing allows single-person installation without additional adhesive. It also serves as an anti-rattle and vibration-dampening material on automotive and equipment panels in cars and trucks.

Compatibility

Designed for use as a sealing and weatherstripping solution around windows, doors, window-unit air conditioners, refrigerator and freezer door perimeters, and as a vibration-dampening strip on automotive and truck panels.

Installation Notes

Installation is performed by HVAC technicians, appliance service technicians, or general contractors depending on the application. Before applying, clean and dry the mounting surface thoroughly to ensure proper adhesion. On HVAC or refrigeration equipment, power down the unit before accessing door or panel perimeters. Avoid stretching the tape during application, as this reduces effective cross-section and may cause the adhesive bond to fail prematurely.
