Anyone know a source (Australia?) for co2 compatable O-Rings. I have to replace them in a co2 valve on a cylinder that is used on an aquarium. The original seals seem to be very poor quality and fail quickly. Had a new spare cylinder and used the valve internals from that the first time the O-Rings failed but they didn't last very long. I need .375 X .500 O-Rings. The first set of seals blew apart during filling and the second set seem to have shrunk.
