System couplings

System couplings (BDA and BMA)

The PLEXOR® test device is connected to a gas station by means of specially developed, safe system couplings. The system couplings consist of two parts. One part is permanently installed on the measuring and test positions on the gas station; the other part is connected to the PLEXOR® test device by means of a flexible stainless steel hose. A union nut facilitates easy and safe connecting and disconnecting. Gas cannot escape during connection and disconnection operations. When disconnecting, the permanently installed system couplings automatically return to the operational position.
