Hi guys. I have removed the radiator in the lounge to be able to plaster the walls. Now, one radiator tail is connected up to the valve via a union nut and the other radiator tail via a compression olive. Idially when i hang the rad back to the wall i would apply a couple of turns of ptfe on the olive but as i can not push back the nut any further because its back already touches the rad and therefore i do not have any room to reach the olive and apply ptfe, i wondered what i can use on the olive to prevent any leaks. I was thinking of applying liquid ptfe on the olive but i have never used it and i do not know if i have to leave to set overnight and whether it would work on the olive. Any suggestions greatly appreciated. Thank you all.
