My local has had a lot of work done replacing gas pipes from the meter to other areas/appliances. The main 28mm pipe from meter is visible in corner of bar area from floor up to the ceiling. It is standard copper tube and end feed fittings. I notice they haven't been soldered, and there is a dark substance where you would expect to see the usual solder 'ring of confidence' where the pipe enters the fittings.
What is this likely to be? Just For Copper adhesive? Wasn't aware you could use it on gas if it is.
