Drip from central heating additive vessel. Does it unscrew? I can’t budge it.

View attachment 44104I’ve tried unscrewing this thinking I can use ptfe tape and re-screw it, but it’s not budging. I don’t want to force it if I’m wrong and it doesn’t have a thread. Does anyone know p

lease?

Looks like and old style magnetic filter.
Not one I have seen before and the picture is terrible.

Thanks for all your replies. I’ve added a few more pics. It’s in the cold in pipe to the boiler. If it does unscrew, I’ll have to wait for my son to come and try.
