Glavanized steel pipe to copper adaptor

[camerart]

Hi,
I need to convert an old cast iron galvanised pipe to copper, on the incoming water mains.
I may be able to dig down and find the last thread underground to connect to. As this could be difficult due to space, I may need to fit an adaptor to the steel pipe, cut just above ground. I seem to remember a compression fit, is this correct?
I've read that care must be taken when connecting two different metals, does the apadtor allow for this?
Cheers, Camerart.

I have never to do anything other than use an existing screwed connector on a steel pipe.

If fact I am not aware of any connector designed specifically for that purpose but someone may know of one.

Many "O" ring connectors could probably be made to fit but might be a bit of a bodge if not specifically designed for that use.

Hi,
The Philmac looks ok, but it shows plastic to copper. I've asked them to clarify it they will connect Steel to copper. Would a building inspector pass them?

What about a long screw?

They have stopped testing us on long screws now!

Hi,
Fitted and working ok. I would recommend them.

I would also recommend measuring the pipes correctly. Having turned off the water in the street, so both me and my neighbour were OFF. I found I had the max 27mm version and my pipe is 28mm. I managed to open it up enough to fit (I'm sure it's not now guaranteed!!)and fit itwith difficulty (phew).
