The dreaded alkathene

[townfanjon]

ehup peeps , anybody know where I can get hold of a mains alkathene fitting to copper and liner .
No local merchants stock them the last one I needed got posted from Northern Island , but it was years ago .
Had a quick look on BES and cant find any.
Down to a bad experience with a philimac type fitting I am reluctant to use another but realise I may have to .
Thanks in advance

I've done it three times, using a fair bit of PTFE, and 15mm as a pipe insert. But was my pipe same the diameter as yours?

Have you put a vernier around the pipe so you can tell the exact diameter?

Yep measures 21mm so should be able to sort something from Mr Kopsta’s merchants.
