ABSTRACT:
In an oil-filled apparatus, such as a transformer, having parts between which pressure is to be applied, such pressure is produced by providing between the parts bodies of an elastomer which absorbs the oil and expands as a result of such absorption. Such bodies may be used between windings and cores or as a seal between a transformer lid and a flange.
