Hi. Very much a DIY’er but I’m installing a new radiator and just a bit concerned that when I’m screwing in the inlet valve to the radiator, the fitting that goes into the radiator thread has no sleeve to tighten it up to. As shown in the photo it would just keep screwing into the radiator, is that right?

It should be a taper thread (male fitting) so it tightens into the female. However, there are a lot of foreign radiators that have too slack a female thread. This is found a lot on designer rads and towel warmers in my experience.
I would use loctite 55.
Others will have their own ideas.

I usually use 17 wraps of ptfe for rad valves, back in the day when things were machined well.... I used the 10 wrap rule.

13 wraps of ptfe, why 13. The first one I did I wrapped it about 4 times and it leaked. I asked a plumber who said he wrapped it 13 times because his brother who was a plumber taught him that and he'd never had one leak. Make sure you wrap it the correct way so that it doesn't force itself off when you are screwing it in.
