Hydrogen breakaway coupling TSA1 H₂ with gas recirculation, female thread

  • The WEH® TSA1 hydrogen breakaway coupling offers additional safety for your car fueling station. The breakaway is installed between the dispenser and the filling hose resp. filling and venting 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 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.
  • The WEH® hydrogen 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.
