Unions are a necessity when using screw together pipe. Anyone who says
that they are not allowed are just full of shit. Hell , look at your
meter, you'll find at least two of them there.

Actually as unbelievable as it may seem unions, are not allowed (per
current code) even in accessible locations, except at the meter. A
left-right coupling is required.....which serves (more or less) the
same function as a union but uses tapered thread.
That said, my 1930 (worked by professional plumbers up until 1979) gas
supply has a few unions .....no problems so far. :)

Well some of the unions out there now suck, I tried some with a air system
piping it leaked where they joined up, like it was not a good fit had to use
pipe dope on the mating surfaces to get a good seal.
