WEH® Adaptor Nozzle TK4 CNG NZ
The NGV1 standard is not yet in use in filling stations and vehicles in all countries.
To allow refueling between the NGV1 standard and other country-specific standards, WEH offers a range of adaptor nozzles.
To refuel NGV1 / ISO 14469 vehicles at filling stations with the NZ standard in China, South America, Southeast Asia etc., WEH has developed the TK4 CNG NZ adaptor nozzle.
Operating the nozzle is quite simple. The adaptor nozzle is simply positioned straight and pushed onto the receptacle. The clamping jaws of the TK4 CNG NZ firmly clamp the receptacle. When the nozzle is connected, the integrated shut-off valve opens – the pressure-tight connection is established.
Unlike the frequently used ball coupling, the clamping jaws of the TK4 CNG NZ leave no marks on the receptacle.
Thanks to the elongated design of the adaptor nozzle, even receptacles that are difficult to reach can easily be refuelled.
