Old Hep fittings?

[Duckwobble]

Hi,

Thanks in advance for any advice!

I'm helping a friend with his water pipes, and I'm wondering about the grey fitting in the picture.

We just bought some HepKeys which successfully dismounted the white fittings, and I'm wondering if the keys would also dismount the grey fitting, as I'm having trouble with it!

I'm thinking there might not be enough pipe to get a good grip?

So the question is: can the grey fitting be dismounted, or is it being stubborn because the pipes not long enough?

Thanks again!

Just tried the Hepkey with this fitting, also to no avail.... so maybe I'm right in thinking these grey fittings are just a permanent fitting, or is there is a different tool used to remove them?

As above these are not de mountable and will need to be replaced if anything is altered. Kop
