Monoblock tails to plastic pipe

[Temp]

The monoblock tap I'm fitting was supplied with tails intended for use with copper pipe (eg compression and metal olive). I'm using JG Speedfit 15mm plastic pipe and the obvious thing to do is replace the supplied tails with these..

However these are plastic and ive always used metal braided flexible hose.  

 

The Hep20 tails are metal braid, can you safely use Hep20 fittings with JG pipe? 

 

Failing that could I remove compression nut and olive from the supplied tails and mate the result with one of these..

Looks like the JG tails might be metal with a plastic coating. I'll go take a look and if so I'll go for them.

Easier option, use the supplied tails and replace the (assumed) brass olive supplied with a copper one. That can be compressed directly on to the plastic pipe. Remember to still use a pipe insert.
