Product review (1 stars): Buy the GE WR17X20862 instead! Save over $100
As other reviewers have already stated, if your fridge calls for this part, you can save over $100 by purchasing GE WR17X20862 instead. I found the easiest way to make the cheaper part work is to purchase a 1/4" coupling (John Guest #PP0408WD) either here on Amazon or at the local home improvement store. One of the 2 water lines works fine (the line that goes from the house to the filter housing) but the other water line is too short. If you use a sharp razor and the 1/4" coupling you can easily splice the line. The coupling costs about $5. This is super easy to do and a big savings. Using a razor makes a much cleaner cut than using a side cutter or other tool.
Another minor difference between the 2 parts is the cheaper part does not come with the small bracket that is used to secure the housing to the inside of the fridge. The old part can transfer over and be used. My fridge is GE PFSS6PKXGSS
