Hi,
I am replacing a radiator valve with a 15mm TRV one. The only prpblem is that the pipework is 8mm microbore. I have bought a single piece 15mm to 8mm reducer which fits inside the 15mm compression fitting on the TRV nicely and forms a flush fitting where the pipe would enter. The only thing I am not sure on is do I need anything to stop this leaking. There is no room for a 15mm olive, but do i need to use any PTFE or jointing compound instead - i can't really see how it would be leak free otherwise...
Thanks
