Hydrogen breakaway coupling TSA5 H₂ for truck and bus fueling stations 35 MPa

  • The hydrogen breakaway coupling type TSA5 H₂ (bus/truck) offer additional safety for your fueling station. The coupling consists of a receptacle and a nozzle which are installed between the dispenser and the fueling hose.
  • 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 and protect your dispensing equipment against damage.
  • The detached coupling can be easily reattached and placed back in service after having been function tested. 
  • The integrated filter system provides clean hydrogen and is easy to maintain.
  • The WEH® breakaway coupling consists of a coupling body, a receptacle insert and a gas recirculation with check valve.
  • On request WEH also offer complete nozzle-hose-assemblies consisting of a fueling nozzle, a hose set and a breakaway coupling.
