Hi Jgst, thanks for getting in touch and apologies for the delay in getting back to you.
Yes, the Hep2O sockets will fit directly over the copper and leave you with a 15mm Hep2O socket for 15mm plastic.
Hope this helps, don't hesitate to be in touch if there's anything else you need to know.
Thanks, Hep2O team
