What size is this rad/valve connection? picture included

[ShaunCorbs]

It should fit as it's a standard 15mm nut and olive

I hear what you're saying Shaun but they're too small. Just to clarify, I'm talking about the connection/union between the trv and rad. Given that the trv is deffo 1/2 bsp as it's stamped on it, shouldn't the union also be imperial and not metric. The union is obviously bigger than 1/2 bsp, so could it be 3/4 bsp?

Surely the cap that Shaun is in about screws straight onto the valve not the tail for the radiator?

Correct

If it's the tail end you want op it's a 1/2 cap you need

Correct

But I've already tried 1/2 and it's too small. Could the union be 3/4 bsp?

It's the union between the rad tail and the trv that I'm talking about

Yea have you tried my nut yet ?

There are so many things wrong with that sentence that I am going to leave it there.

Not physically tried, only offered it up
