Primaflow push fit

[bedtester]

Is there anyway to demount this primaflow push fit, I have a tool like this but don't think it'll do it.
If demounting is impossible, best way to remove it without ruining the pipe

That's the demount toolset they sell for the Primaflow, so they should work

Yep definitely demountable with the correct tool

This fitting definitely not demountable, no release collet and you can't access the sharks teeth.

If this helps others, I buzzed it off nice and square and clean just on the live side of the centre, then used what was left as a straight connector and soldered a new peice copper pipe. I could have pushed the collar down but what I tried worked well.

Sorry didn't take photos.

The o rings looked in perfect condition, years left in them and already at least 20 yo
