This genuine Samsung gasket assembly (DA97-17218H) is designed for your refrigerator to maintain an effective seal, preventing warm air from entering. Over time, a failing gasket might cause your refrigerator to run inefficiently. Smooth out any folds or creases by gently warming the gasket with a hair dryer or soaking it in warm water. Before starting the replacement, store any food that could spoil. Verify your refrigerator's model number for compatibility before purchasing.
