WEH® Inline Breakaway Coupling TSA6 CNG - Product family

for bus and truck fueling stations (Inline-Installation), 200 bar / 250 bar 

With type TSA6 CNG, an inline breakaway coupling which is installed inbetween the filling and venting hoses, is now 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 hoses 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 breakaway device consists of a coupling body, a receptacle insert and an optional gas recirculation. We recommend the installation of a type TSF5 CNG filter when using the TSA6 CNG inline breakaway coupling. The filter protects your system from dirt ingress.

We also offer complete hose assemblies consisting of a fueling nozzle, a hose set and a breakaway coupling (for complete hose assemblies see respective fueling nozzle).
