Why the hissing noise is necessary

Who has not experienced or heard it before: You turn on the valve of the gas cylinder and it hisses. Indeed the operator does not smell any leaking gas, but there will be still a little queasy feeling. Is something wrong with the gas cylinder? Maybe the hose line is leaking?

To dispel any concerns, GOK has attended the subject matter and explained it in the latest video tutorial. Generally you will not have to worry about if it hisses while opening the gas cylinder valve. On the contrary: it is even necessary for the operation.
