Those are the industry standard numbers for o-rings, i.e. you can get a #003 in any hardware store.

For the Crosman numbers, go here and find your application or gun model # and look at the parts diagrams.  http://www.crosman.com/cs/manuals/crosman-pistols (http://www.crosman.com/cs/manuals/crosman-pistols)

No problem and... o-ring dimensions are typically universal but... materials differ; Buna, Viton and other materials. Not a big deal for 13XX and 22XX guns but, huge deal with HPA and PCP guns.

Here's a good link for the usefullness and selection of materials in o-rings   http://www.marcorubber.com/material_chart.htm (http://www.marcorubber.com/material_chart.htm)
