Here is a photo of a NG hook up. I happen to have 3/4 pipe comming to the area. And I happen to have a 3/4 ball valve so that was used. I had to use two reducers going right to left to the flash arrestor. A pipe to hose adaptor then the hose. All of this done professionally. Using pipe compound and not tape.
Have a professional do the work don't try it your self. This is not a do it yourself project.
