I have a common issue where the new radiator isn't quite the same width as the old one. Have got hold of some 30mm extension pieces and fited them but they leek. I have attached a picture for reference.
So firstly I removed the existing radiator tail. I then wound some PTFE tape around the 'male' end thread of the extension piece and screwed it into the rad. I then wound some PTFE tape around the male thread on the existing radiator tail and screwed it into the extension piece. I then connected this assembly to the TRV one end and the radiator valve at the other by way of the compression fittings.
The leak is coming from the following areas: Between the radiator and the extension piece and the extension and the exisiting tail..... A fast steady drip would best describe the leak. The connection between the TRV and radiator valve are both sound so the issue is clearly iwth th eextension pieces. You will see from the picture there is no rubber gasket present on the extension piece. That is how it was sold and supplied but not sure if there should be a gasket.
So what am I doing wrong and what other than PTFE tape should I be using? Also I wound the PTFE tape round about 5 times, was that not enough?
