This fitting is for all built-in standard and tall tub dishwashers built by Whirlpool (Whirlpool, Maytag, KitchenAid, JennAir, Amana, Magic Chef, Estate, Inglis, Roper, IKEA, Crosley and Kenmore/Kenmore Elite). It replaces an older 3/8 in. MIP connection, with a newer 3/4 in. hose connection. The brass construction ensures that you're using a quality product for your project.
