trv valve and radiator tail

[Mrxman]

Hi There

I have a plumber coming in next week and just trying to make sure I have what we need.

I've bought a TRV valve and straight out of the box the tail part (the part you put ptfe tape on) is loose. Meaning, when I put it into the valve part there doesn't seem to be a way of tighten it. How do you actually tighten it? How does it work?

Hope I make sense.

If the plumber doesn't know how to do it , find another plumber !!
The nut tightens against the olive ,compressing it onto the radiator tail.

I got it, thank you. I was trying to screw the nut on by hand (doh) which didn't work. Used a spanner and all is good.
I was a little concerned I might have had a faulty valve.
