The Refrigerator Water Line Installation Kit supplies water to refrigerator components that require water such as the ice maker and water dispenser. This kit includes 25' of PEX tubing and 1/4" fittings for ice and water hook up. This is a universal item that can be used across several brands; check to see if your model number is compatible. Replacing this accessory will require basic hand tools, but no disassembly of the appliance or repair experience. Turn off the refrigerator s water supply before you begin.
