The Nor-Lake 118634 Double Sweep Gasket is a replacement sealing component designed for compatible commercial refrigeration equipment. Measuring 38.75 inches, this gasket helps create a seal around the appropriate refrigerator door when correctly fitted. A properly functioning door gasket helps reduce unwanted air exchange and supports consistent temperature maintenance inside the unit. Over time, a gasket may become worn, cracked, loose, or damaged, which can affect door sealing performance. Replacing a faulty gasket with a compatible part supports routine refrigeration maintenance and helps the equipment operate as intended. This component is useful for restaurants, commercial kitchens, and foodservice facilities. Before ordering, verify the part number, gasket dimensions, and refrigerator model to ensure a proper fit.
