First, you look at the parts diagram on FX site, here is the link to Impact:

All orings will be metric and will specify hardness of rubber in the description, example: C38 19731 O -ring 2×1 NBR 90

C38 is the location on the diagram, 19731 is internal part number, 2×1 means 2mm diameter and 1 mm cross section, NBR 90 means hardness, Buna 90

So when you go to search for this oring, you go to metric-b90-orings category first, then filter by cross section, 1mm, then find outer diameter 2mm
