It has seal with one install of the product and no problem. It's to bad they have to sell it as a set of two.

Good product, the shaft seal was challenging to install, I still have a small leak so I would recommend replacing the plastic gear when you have it out. Next time I will probably just replace the whole assembly for a few bucks more.
