The Frigidaire 137566000 Door Bellows creates a flexible seal between the washer door and tub to contain water during wash cycles. This replacement bellows is fitted around the washer opening and forms a tight barrier when the door is closed, preventing water from escaping through the front of the appliance. Its flexible design accommodates the movement and vibration of the washer while maintaining contact with the door and tub surfaces. A torn, cracked, or deteriorated bellows can cause water leaks and moisture buildup around the door area.
