Product review (5 stars): Perfect Replacement Part
Exactly what was needed to repair my ~1995 kitchenaid dishwasher.

This fits DOZENS of different KitchenAid, Whirlpool, and Sears/Kenmore dishwashers made from the 1990's to current.

The tube is 7-3/4 inches long.  When new, it is a very flexible, rubbery material.  On most dishwashers, it attaches to a round tube at the back of the rack, and an oval tube in the center of the rack.  As it ages, it gets hard as a rock -- so your old broken one may LOOK like it is pre-formed hard tube that is round at one end and oval at the other.  But trust me, it started out as a flexible oval from end-to-end.

Installation tip:  Lubricate the inside ends of the tube with a little liquid dish soap and it will slip onto the mating tubes (round and oval) very easily.
