Plastic pipe into compression fittings?

[Temp]

Is it ok to run Hep2O plastic pipe into compression fittings like this designed for copper?

With pipe inserts obviously.

 

I know there is a pressure reducer with 1/2" brass ports and 1/2" brass to HEP20 adaptors.

I prefer to convert to copper for compression fittings, also I did not get on with the reducer insert (22 to 15mm) that came with this PRV , it leaked despite several attempts (yes I used one of these in my build).

Yes although I tend to use a copper stub and then use a straight connector or an elbow

Thanks. I'm adding a pressure reducer into an existing plastic pipe so think I'll go with this one..

And a pair of adaptors..

am I missing something, what pressure does it reduce too.?? Does not say, no gauge either. ?

Normally they are preset to 3bar but I guess I should check.

In the end I remembered that the thread on a 15mm compression fittings was 1/2" BSP so a much better option was a pressure reducer with compression fittings (removed) and a pair of these tap adaptors..

I will be interested how you get on with that.  A tap connector expects a nice crisp flat shoulder and seals with a fibre washer, not the tapered profile where the olive would go.

Yes was a bit concerned but it looks fine on the Honeywell regulator. The tap connector I have also came with rubber washers.
