Product review (1 stars): Metal Hub Doesn't Mean It's Heavy Duty
I purchased two of these couplings so that I would have a spare. The first one failed during the second batch of wash. The second one and the replacement coupling sent when I notified the vendor all failed in about the same time. In all cases the metal hub came loose from the plastic sprocket. To make sure there wasn't something wrong with my washing machine causing the failures I purchased the all plastic coupling without the metal hub. It has been working well ever since. I spent a lot of time replacing couplings. Don't buy this coupling. Buy the one without the metal hub.
