Thread type: W Cylindrical - gas cylinder valve thread DIN 477
Gas cylinders are according to the standard EN 962 transportable gas cylinders, valve protection caps and valve guards for industrial and medical use.
Depending on the type of gas there are different screwed connections to avoid confusion. The use of adapters is expressly forbidden in Germany.
