Help sourcing imperial fittings/adaptors

[Gary M]

I have a 27mm OD semi-flexible black pipe (PE?) feeding mains water to an annexe. I am struggling to source compression fittings to adapt this to metric pipe so that I can use standard modern components downstream. I belive the installation is about 50 years old. Is this what used to be 3/4" pipe?

Yes, 27mm OD is likely the old 3/4" imperial pipe. To connect it to modern metric pipes, use a 3/4" imperial to 25mm metric compression adapter. Ensure the fitting is WRAS approved for UK use. Verify the pipe material (PE) before fitting to ensure compatibility.

Thank you for the prompt post! I would be grateful for suggestions on where to source those fittings.
Also there is only a few inches of pipe protruding above ground and any identification has long worn off. From reading around, it seems possible that it is a form of polyethylene (MDPE?) that was commonly used for undergound pipework in domestic installations in the 1970-80s. Any suggestions on how to identify it better?

What do you need to get to eg copper 22mm or 25mm mdpe / alk ?

 

[Gary M]

Copper - 22mm or 28mm because it needs to feed not only the annexe but also two similar 27mm OD pipes feeding outside taps without too much restriction.

Thanks ShaunCorbs - most helpful. I guess dedicated fittings are no longer available, so these universal fittings - though expensive - are the only way to make the join.

 

[ShaunCorbs]

You could probably still get brass fittings but they would be expensive I would suspect over £100 per fitting

Ouch! I'll go with the universal designs!
Thanks again
