    I had a leaking Accor flo-tite push-pull valve that was connected to dishwasher supply line.

    The plumber came and replaced it with a compression shut-off valve, but was going to charge $250 to connect to dishwasher.

    So, I purchased universal dishwasher kit and have so far be unable to attach to shut-off valve. As seen in picture, the hose is 3/8 inch and it is too big for the valve. Therefore, the valve would have to be 1/4 I would think. However, I’ve tried purchasing a few connectors (in picture). But they have similarly not fit the shutoff valve.

    I know this extremely basic, but I would greatly appreciate any help on which specific connector I need to purchase.

    Thank you.

    I believe what you have is a 1/4" "icemaker" valve. Looks small to my eye, at least; and the end of a dishwasher supply just fits right on a standard 3/8" valve.

    I'd just get a 3/8" compression valve, and swap the bodies around. Keep it simple.

    Either the plumber was stupid/incompetent, or he wanted to "punish" her for not paying him to connect the dishwasher. Replace the valve.

    I agree that changing the valve is the correct solution, and the plumber should do it without charge since he used the wrong valve in the first place.

    But if for some reason you are stuck with the existing valve, and if it is in fact a 1/4" compression outlet like for an icemaker, a kludge would be to use a short 1/4" icemaker supply line and a 1/4" x 3/8" compression coupling, to which the normal 3/8" supply line could be attached:
