    Is it possible to buy just the second stage and hose w/o the first stage? I need to add a second regulator and do not want a yellow version. Thanks

    yes, you would have to contact a shop and ask for it specifically though as it isn't a standard stock item

    As above. It's no problem, I've done it multiple times.

    I believe the main difference between 50 and 100 is the fine tuning on the adjusting screw.

    BTW, ATX-40 is a lot cheaper unless you prefer adjusting screw.
    The diaphragm on ATX is smaller than TX and XTX but the main moving part is the same.

    I prefer the XTX 50 to the XTX 100. The only difference is in the materials. 50 is mostly plastic. It still has venturi and adjustment.

    What do you mean? Both 50 and 100 have adjusting screw. Service kit is the same for both.

    He's right. It's just materials on the casing etc that are different. Both regs are the same.

    TX, ATX, XTX and Egress 2nd stages all use the same service kit(AP0219). I never need O-ring AP1159 and AP5711 for my T20, ATX40, TX40 and TX50 2nd stage. But my ATX-200 needs both of them.

    I must admit that I have no knowledge on FST and its corresponded 2nd stage. Only assuming both 100 and 200 2nd stage are using the same adjusting screw.

    The adjusting screws used on TX-50 and ATX-200 are different:
    1. TX-50 uses only adjusting screw(AP2029) +AP1409 O-ring
    2. ATX-200 uses adjusting screw(AP6577/S) +Adjuster spring(AP6578) + three O-rings(1159, 1409 and 5711).
    While ATX-50 uses adjusting screw(AP6577/1). No idea what is the difference between 6577/s and 6577/S.

    Here you provided link to XTX line, so I thought we were talking about XTX 50 and XTX 100.

    Ok, I don't know about TX or ATX line (my service course is in March), but according to manuals I have XTX50/200 use same part number adjusting screw AP6577(in older manuals referred as AP6577/B) , XTX 100 is AP 6577/S. All of them require o-rings you mentioned.
