Leaking Radiator Connection

[CSutton]

Hi all,
I live in a 5 year old house and have a leak which has started from one of the pipes into my radiator. With Christmas round the corner can anyone tell me the part(s) I need to replace please. Have tried pushing the connector in further but doesn’t stop the leak. Thanks, Chris

It needs dismantling and remaking, just one point to note pushing the plastic collar in actually releases the joint.

Yours is rather odd being part brass and part plastic but the principle is the same.
PS I would replace the fitting as chances are the O ring inside was damaged on fitting.

That’s great, thanks footprints.
