This is a used upper rinse arm taken out of a GE dishwasher.  The part number on it is 16505705.  Please check that number to see if it is compatible with your dishwasher.  I couldn't find a list of compatible models.  This one is white in color.  It could use some more cleaning, but it isn't cracked or broken.  Please contact me if you have any questions and thanks for looking.
