Total reliability in harsh environments

Hydraulic systems operate at high pressures to create enough force to move heavy machinery. It’s essential that these systems are securely sealed to prevent injury. Koenig expander sealing plugs have in field failure rates below 1 ppm.

Koenig sealing and flow control solutions are used in fluid systems for mechanical engineering, conveyor technology, and mold construction.
