Product review (1 stars): Didn't fit
Piece did not properly fit a frigidaire galaxy dishwasher as advertised.  Return policy is onerous, buyer beware.

The threads and fittings are slightly different, by disassembling and re-assembling it with parts from the old piece I can at least attach the spray arm but as one might expect it leaks at the fitting rather than all the water going into the spray.
