I know they are bunna the thick ones like what go between a tank reg and bottle. I don’t know the exact size but I was able to source some from my local hardware supply store. When the sit in the oring channel they stick a lil past the face so it seals when clamped down against the body. They are a lil thicker then your standard paintball orings.
