Fuelling products must be adapted to country-specific standards as the NGV1 standard is not yet used worldwide. We, therefore, adapted our TN1 CNG fuelling receptacle for refuelling vehicles with NZ or GOST standard at NGV1 fuelling stations in China, South America, Southeast Asia, Russia, etc. We offer TN1 CNG adaptor receptacles for connection to the NZ or GOST receptacle of the vehicle. The adaptor receptacle can also be permanently installed in the vehicle.
