WEH® Breakaway Coupling TSA1 H₂ 70 MPa - Product family

  • for car fueling stations
  • for direct installation at the dispenser

The WEH® TSA1 H2 70 MPa Breakaway Coupling was developed specifically for 700 bar technology. The breakaway is installed directly at the dispenser of the car fueling station.

In the event of accidental deployment, e.g. driving a vehicle from the dispenser with the nozzle remaining in the vehicle fuel port, the coupling will separate the connections between dispenser and hose sealing both ends. This protects largely the receptacle, the fueling nozzle and the dispenser against damage.

The detached coupling can be easily reattached and placed back in service after having been function tested.The integrated filter provides clean hydrogen and is easy to maintain.

WEH® Breakaway Coupling consists of a coupling body, a receptacle insert and a dispenser mounting.
The TSA1 H2 70 MPa for fueling nozzles with data interface additionally contain a data cable for the data interface.

On request we also offer complete nozzle-hose-assemblies consisting of a fueling nozzle, a hose set and a breakaway coupling.
