The W11504449 Whirlpool Refrigerator Lokring Tube Coupler is an aluminum reducer that connects refrigerant lines of different diameters (4mm to 2mm), maintaining system integrity and proper refrigerant flow.
A leaking, cracked, or disconnected coupler causes refrigerant loss, leading to temperature imbalances, compressor failure, and complete system shutdown.
This genuine OEM component ensures secure, leak-free connections essential for efficient cooling performance.
Also known as a Lockring Coupler, this precision fitting is compatible with Whirlpool, KitchenAid, Maytag, Jenn-Air, Amana, and affiliated appliance brands.
Proper refrigerant circulation depends on reliable couplers—verify your refrigerator model number before ordering to confirm compatibility and ensure optimal cooling restoration.
