    Sorry for bring up YAORQ (yet another o ring question), but I have lifted the orings from the FX parts diagram and tried to make note of what the o-ring actually does.  Can anyone double check this and confirm what one oring does that I can’t determine?  It’s the 2nd one in my list below (D9).

    http://www.fxairguns.com/wp-content/uploads/2015/10/Royal-Drawing-and-Partlist.pdf

    C4 19098 O-ring 18×4 NBR90  (shroud area)
    D9 – X 5112 O-ring 5,28×1,78 NBR70  (??????)
    D17 5105 O-ring 9,3×2,4 NBR90  (hammer spring area)
    D19 2529 O-ring 4,3×1,5 NBR70  (breech seal)
    D20 2528 O-ring 1,5×1 NBR70  (probe seal)
    D24 HP 5111 O-ring 2,5×1,5 NBR90  (hammer spring area)
    E1 – 5,5 5108 O-ring 5,28×1,78 PUR70  (regulator area)
    E2 5112 O-ring 5,28×1,78 NBR70  (regulator area)
    F4 1504 O-ring 4,42×2,62 NBR70  (rear of probe)
    G3 4528 O-ring 7,66×1,78NBR70  (bottle fill connector)
    G4 19088 O-ring 15,88×2,62 NBR90  (bottle fill connector)
    G8 5107 O-ring 2,9×1,78 PUR90  (bottle fill connector)

    And if anyone can map these orings to specific vendor part numbers I would be most appreciative!  

    Thanks!

    Isn’t that the little o-ring that goes in the recess under the stock mounting boss?  Hard to see but it’s there.

    Wow!  That’s quite a system!  It looks like you can open your own store!

    OK, I’m a dummy and here is a correction…

    The parts diagram in originally linked to on the FX site is an OLD Royale without a regulator.  Trevor from Utah Airguns confirmed that I need 2.4mm CS X 11.6mm ID Metric Buna-N 70 O-rings for the regulator.

    English size of regulator o-ring:
    .094 CS x .457 ID x .646 OD

     I ended up getting a bag of these on Amazon I believe,  they work just as well as the factory ones.

    A friend had some o-rings of a slightly different size and I got lucky.  They work GREAT on my FX Royale regulator! 

    Before:

    After:

    Size I used = 2.4×11.8mm
    Spec size = 2.4×11.6mm

    That looks like an unregulated shot string. The (before)

    Yup,  And what was interesting was that the o-rings that were on the regulator when I shot that crappy string looked perfect.  Not one nick or scratch on them.  So i guess that a visual inspection of an o-ring does not tell you much…
