FAQ: Why does this kit include 4 different o-ring sizes. Can’t I just buy the one size I need for my exact filter model?

Answer: Since there are multiple revisions of each of these filter housings, it is impossible to tell which o-ring you need until you have all 4 sizes on hand. For example, if you have a WH5 filter housing, yours may take any one size within this kit. Offering all of the o-rings in a kit is the only way that we (as well as the OEM) can guarantee that you get the correct o-ring for your exact submodel/revision of the filter housing you have.
