Tuning ……..,

I would contact HUMA directly to inquire about the exact size options.
Have you tried using divers grease? It sometimes helps.

The Huma reg in my Royale 400 came from Trenier Outdoors. It came with a rebuild kit, which includes all the O rings. Unfortunately, no sizes are indicated. If you call, they might be able to give you the sizes. Meanwhile, after my dog walk, I'll do some measuring and comparing with all the O rings I have for all my rifles. Measuring is difficult, since the O ring sizing is by .01 mm, or .00039", difficult to measure precisely. I'll see what I can come up with and post later.

I could not find a match in my O ring supply. Here is what I get when attempting to measure to the nearest .001" and converting to metric:
12.0 x 1.47 mm
12.95 x 1.88 mm
Those are probably not exact, but I think if you choose a size up and down one from these estimates, you will have it. Of course Trenier might have the specs on hand. Good luck.

I can empathize. When I put the Huma reg in my Royale 400, I must have removed and adjusted it 10 times before getting the tuning right. I had to replace the seals in the bottle adapter and stock attaching screw body, after draining and disassembling so many times. Luckily, a year later, it's rock solid, and still the only FX rifle I will own.
