O-ring specs @ tube & gauge block, RS1 please?

[JamesD.]

Need to know the size & durometer of that last O-ring that goes over air tubes threads and is sealing the tube to the gauge block. Mine is missing due to Altaros reg install, which needs a rebuild. I plan on taking reg out, testing heavier pellets until kit gets here. I may leave it out if the RSI likes the newer JSB 25.43 .22's

Thanks ahead of time fellas.

more here. I think I heard the blizzard and rainstorm are essentially the same so should apply?

I read it all but no exact dimensions on my missing O-ring that was taken out so reg can equalize. Just need ID, OD, metric or SAE, and that ones recommend durometer.
