Product review (5 stars): Simple and easy fix!
This worked great on my GE GSC3500N10WW Dishwasher. The uncouple has been leaking for a long time, due to a small hole in the gasket, and I could never find just a gasket replacement for it (someone should sell those!), so I just lived with it. Eventually the uncouple would just blast off the tap constantly, which was somewhat dangerous, messy and wasteful. This solved all my problems for far less than buying the whole replacement uncouple and hoses (cannot believe they expect people to pay $70+ for such small repairs such as a gasket).

I only needed the gasket and the little plastic "teeth", both of which fit perfectly despite being listed as a whirlpool product, I think most uncouples use the same design. Thought I would share my model and compatibility as it is a very common dishwasher.
