Hi Danjm, thanks for getting in touch and apologies for the delay in getting back to you.
Yes it is, the Hep2O sockets will fit directly over 15mm copper and then just continue with Hep2O pipe.
Hope this helps, don't hesitate to be in touch if there's anything else you need to know.
Thanks, Hep2O team
