Product review (5 stars): Aprilaire replacement part
You can't find spuds like this just anywhere. Hey, it's a part that broke on a old humidifier. They had it. It was easy to find, purchase and they shipped it to my door. You know that old saw. You don't miss your humidifier spud 'till your basement floor is all wet or however that goes. When dealing with spuds I don't think it gets much better than this really.
