Don't mean to resurrect old news...
if I were to use a dispenser from a KD-20, would it fit correctly on a KD-17A/57A?
According to the variants in part numbers as discussed above, yes.
But... the older blue dispenser on the has a wide, flat gasket while the newer white dispenser has a small, round seal.
Does this make a difference, or is this more just a matter of "actually this works"?
Thank you!
