Hi there. I’ve installed a new towel radiator and I’m trying to fit the valves but I’ve come unstuck and need some help.

I’ve bought new angled valves to replace the old ones but I can’t connect them. I think I’m missing something.

They are the right size to screw into the bottom of the radiator, but the valve head is too big so it’s not a tight join

the radiator comes with a connector but the valve dont tighten on them.

See pictures. Apologies if this is something really obvious. Am I missing a connector?

Thanks in advance

Thanks for the reply! Yes you’re right I can screw in the trv and the other valve but not fully tight as the end butts up against the bottom of the radiator

Your picture in post #5 is how you do it.
Slide the valve onto the smooth tail, yes it can just fall off again, but then you tighten it with a spanner and the copper olive is compressed - this not only makes a water tight seal but it also stops the valve falling off!

They can stick quite easily, try a spray with silicone lubricant and then a gentle waggle to get it covered low down too.

I’m not familiar with boiler mate’s but sounds like a stuck motorised valve.
