Zbroia Kozak .22 breech o-ring size?

[TN_Yankee]

I'm getting ready to order some spare o-rings for a few rifles, and need to know the size of the .22 Kozak breech o-ring. I haven't seen it called out on their diagrams (only the .177 is listed). The older Hortitsia seems to share some parts, so it may be the same size; maybe the same with the Sapsan, but I can't find the information to confirm it. I'd rather not order an over-priced "speciality kit" from a supplier if I don't have to.

I think it's 1.5 mm cs x 5.5 mm ID...

you are correct,,, the Kozak .22 breech o ring is 1.5x5.5 mm

Thanks, guys. I knew it would be somewhere around there, though I thought it might be 1.9mm cross section (or 2, depending on their documentation).

One more - the fill probe isn't shown on the diagrams. I measured it as 6x1.5 - does that sound right?

both the fill probe and the fill valve inside the tank use 1.6 cs x 3.1 id mm
I do not remember where I got the size for the probe but I have it written on my o-ring bag
