WEH® Inline Breakaway Coupling TSA2 H₂ with gas recirculation

  • for car fueling stations
  • Inline Installation
The WEH® TSA2 H2 Inline Breakaway Coupling which is installed inbetween the filling hose resp. filling and venting hoses, is also available for bus and truck fueling stations.

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 WEH® Breakaway Coupling consists of a coupling body, a receptacle insert and a gas recirculation.

We recommend the installation of a WEH® TSF2 H2 Filter when using the TSA2 H2 inline breakaway coupling. The filter protects your system from dirt ingress.

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