Yes. Rubber expansion joints can operate in vacuum conditions. However, the value of vacuum depends on the type and diameter of the expansion joint. As the diameter increases, the value of a permissible operating vacuum in rubber expansion joints decreases. So, when the rubber expansion joints, especially those with larger diameters, are to withstand such operating conditions, they are additionally equipped with internal vacuum support rings and spirals made of acid-resistant steel. As a result, the rubber expansion joints, even those with larger diameters, can operate in vacuum conditions which are close to full vacuum.
