Buses and trucks running on natural gas have to be serviced and checked regularly, a process involving the discharge of their pressurized fuel tanks.
The WEH® TK21 CNG defueling nozzle has been designed for this specific purpose.
The defueling nozzle is simply engaged onto the receptacle of the bus/truck and the knurled spindle fully turned until the receptacle is fully open. Discharge can now take place through the lateral media discharge vent.
