There are 5 inlet ports (and/or dummy ports) on the back of the upper spray arm, each fitted with an O-ring type of gasket/seal. Some of those rings have fallen off over time.

How critical are those gaskets to the proper functionality of the upper spray arm? The dishes on my upper rack seem to be getting clean so I would prefer not to buy a whole spray arm assembly for no good reason, but knowing the gaskets are missing bugs me.

The gaskets aren't standard o-rings, they have a unique design with a lip to create the seal and don't seem to be easily sourced from a hardware store. Of course Bosch wants to sell you the whole spray arm assembly which is ridiculous. Any suggestions on how to obtain new gaskets that would fit, even if they're not made by Bosch?
