8mm copper to 15mm plastic connection

[Tommy o'Toole]

I have recently moved house and would like to move a radiator from a side wall, to one below the window as is more pleasing to the eye.

I understand why it was not placed under the window, as my house is old and has concrete flooring so would be difficult when it comes to the pipework. Anyway... I want it moving.

I have worked with plastic JG speed fit piping in my previous house (15mm), and would like to do the same again. As the radiator is only moving about 2 meters from where it currently sits, it seems a convenient way of doing this.

However, it looks like there may be a problem straight away, as the current pipes are 8mm microbore that I would like to cut and connect to 15mm plastic.

There does not seem to be any metal to plastic connectors for this (unless I'm just not seeing them).

I have however found this at screwfix that might work. Does anybody know if I can connect 8mm copper to 15mm plastic using this:

If this is possible, I'm assuming that both immediate pipes will connect using olives (including olives on the plastic piping). If this is correct, once connected to the 15mm I'm good to go, yes?

Thanks in advance!

Use 10mm plastic as jg do 8-10mm reducers

As Shaun says, though I think your suggestion of connecting via compression is also valid, provided you use the correct pipe insert for connecting via a compression joint to Speedfit (the type without an o ring).
