Connecting imperial mains pipe to metric copper pipe

[Simon]

Good evening gents,

I really could do with a bit of advice....for which I thank you in advance.

To cut a long story short, I need to connect what I think is 1/2 inch (measures just over 0.8 inch OD) steel/iron mains pipe, to metric 15 or 22mm copper pipe. 

The ONLY fittings I can find have a thread for the imperial side....the pipe I need to connect to has no thread....

 

Please, how might I achieve this obviously unusual feat?

 

Thanks

 

Simon

Sorry but first thing is cut a thread on the steel pipe.  I bet that is not what you want to hear.

+1 to cutting a thread or tracing it back to something that already has one.

 

I think these have been recommended on the forum before but I've not used them..

You're right, it wasn't what I wanted to hear....but it kind of is what I expected....

 

Thanks for your help gents, much appreciated.

Then 25x 15mm adaptor.  That’s 14-18, but they may do one to copper on the other side. Just ask your merchant for the nearest combination.

Another vote for the plasson universal couplers. Used a 27-32mm one to connect our new MDPE supply pipe to the existing dented and scored 6lb lead pipe at the stopcock. Easy and solid.

Have you had the lead replaced now?
