Can you use unions to connect gas pipe? Or rather, is it LEGAL to use unions
to connect gas pipe?
Some say YEAH BUT HIDE THEM, some say NO WAY, some say SURE, I'VE DONE IT
FOR YEARS. I was replacing some gas pipe and the guy at the plumbing
wholesaler asked if I wanted to do the connection with a union or a
right-left pipe and fitting (giving me a choice). I've always done it with a
right-left (though I don't like that way) because I thought that was the
code.
Any thoughts?
Thanks

I've never seen any code proscription against unions for gas service.

If I recall, the Uniform Plumbing Code only allows unions at
appliances and at the meter. These have to remain exposed. Anywhere
else you need to use a left-right coupling.
For a more definitive answer, www.iapmo.org has a recent draft of the
UPC available for download, and you can find the actual rules.

That's the only place I have seen them used as well.
I would have assumed the question wasn't for in a buried line,
certainly... :)

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. :)
