gasket

The battery in my Holeshot 3 Hand (Small) has finally gave out; Upon opening up the back case, the rubber is pretty much non-existent. I can't seem to find any info as far as gasket size for the Holeshot Small 3 hand. It's my daily wear and it pains me not to be able to even wear it. I checked...

No real clue what these could be used for, but always a chance someone needs some. O Wire - Gunmetal Dictate 2.0 - Black Chrome Ratchet 2.0 - Pewter Gasket - Brown Tortoise Looking for $20 on each; shipped in the US.

Does anyone have any issues with the gasket squeezing out of the sides of the orbital joint of the Romeo 1, and does anyone have advice to keep it uniform? I do not over-tighten them; I'll set them to be flush, but through the flex of wearing, the gasket will "bubble out". Thanks, Chris
