The Schuck expander is a maintenance-free, self-sealing compensator, which is designed as a freely movable, stored and in and out tight construction. The expander can be used for gas, oil and water pipes. Its maintenance-free operation is ensured by the two self-sealing, separately testable sealing systems, the prevention of the ingress of dirt, as well as the protection of the parts susceptible to corrosion by special machining. The ready-to-install expander with its special design is reusable.
