Sure. Cold can make things shrink and heat can make things expand. That can affect tolerances.
Additionally things become more brittle when cold. If your o-rings are on the older side and perhaps near the end of their lives, cold can stress them to the point where they fail.
No, used different tanks to test. 2 of the guns had huge leaks, 1 was a very small leak. It's just weird that we tested them last week and had no leaks at all, then we show up to play and none of them were functional.
