Russian o-ring problem

[Cavere]

I've been very happy with my Russian for over a month now. But I have run into a problem where the o-ring on top of the chimney gets swollen. This has happened to the extra as well. Because of this I believe that it is not creating a seal and have been getting leaking out the air hole. Any suggestions of what might be causing this and how to fix it or where to get replacement parts?

Thanks.

some have reported that the juice they are using is causing this, I would think about the best you can hope for is hunt down some orings made of different materials or stop using that juice.

Honestly I don't know what juice was in the tank when they swelled.
