How many different size quick connects are there for Aux hydraulics?

Just picked up another skidsteer attachment for my SK820. And I have come across another size of aux hydraulic coupler. Does anyone have a chart, or at least a breakdown of how many different size aux. hydraulic couplers there are between the different manufacturers? Thanks.

    Texas: Try this site it has cross reference to Tomco, Parker and Aeroquip. http://www.imperialinc.com/grp371.shtml Here is the Parker page of couplers. http://www.ematerialhandling.com/hydraulic/quickcouplers/hydraulic/hydr_quickcouplers.htm There is usually a cross reference for most couplers. another site with a chart is here http://www.fittingsandadapters.com/hydquiccoupi.html Hope you find a solution.

    Here is the Case brochure explaining ISO Flat Face couplers. ISO is common among many manufacturers the sizes are explained. If you have flat face and can pick them out from the Case chart you can cross reference to Parker or whatever.

    Thanks for the links. From what I could find out there are 3 main sizes in use. 1/2" bodies for standard flow machines 5/8" bodies for intermediate flow 3/4" bodies for high flow 3/8" seems to be used for a case drain on some machines, but not all.
