I had tried a generic rubber hose, but it was not at all suitable for the Amana, with it's built in rubber coupler. This hose has rigid plastic at the dishwasher end that fits snugly into the washer's coupler. The other end is pliable and could be clamped to the air gap with no trouble. I've been using this hose for a few weeks now with no issues.
