Union on Natural Gas Line in Attic

[fictitious]

You would have to check with your local building code or building
inspectors.

As I personally look at it; would I rather have a union in the attic
where a leak might blow the roof off, or in the basement where a leak
will blow the whole house up? They have to have junctions somewhere
since the pipe is never bent to make turns and it doesn't come in runs
long enough to reach all the appliances.

Also can use a coupling. It is L.&R.(left & right)hand thread.You will
need a Left & right hand threaded nipple also.
May not be easy to find at a HOME______ type store.
Good Luck....... Jerry

A slight change of topic on this, I need to run an extension on my Natural Gas line to
service a small heater in my garage. The line in the house is the usual black pipe with
copper tube to the appliances. I was wondering if any other material is suitable for
running the extension on the line. Cutting an threading iron pipe is going to be sort
of a pain with all the obstacles I have to go around. Copper tube would work but its
rather expensive for the distance. Any thoughts
Thanks Paul

As far as I know, unions are no longer legal for gas. If you do use one
anyways, be sure to use a black one meant for gas, rather than a galvy one.
The difference is the gas kind has a soft copper seat so it seals better.

The right way to do what you need is to buy a special fitting consisting
of a piece of pipe with a right hand thread on one end and a left hand
thread on the other. It comes with a couple that is similarly threaded.

What you do is cut your existing pipe, either thread the cut, or remove and
replace enough pipe to get the size gap needed for the fitting you just
bought, and insert it. With the right/left threads, you can tighten both sides
of the connection at once.

Be sure to check for leaks.

One thing to remember Paul is this the further you go, the larger
diameter pipe you need. My advise is to call a licensed gas fitter.

You both are looking to burn your homes down. First of all a union is a
fitting just like anything else and unless local code prohibits you may
use a union. and actually a union is recommended with a shut off on the
other side so an appliance can be removed easily. If you have these
questions then the repair is out of your league. Please have someone
qualified do the work for your safety and that of your familiy.

You dont want to use Copper pipe for Natural Gas it will eventeally eat
through the pipe and is against code also use a union as long as it will
be accessable in the future if you ever have a leak it will most likely
be a loose union. Stay away from these couplings with backwards threads
they dont sound good at all..
