I'm about to remove a radiator and wasn't clear about how the radiator tails connected to the radiator valves. I found this excellent post from last year:

Reading this, it seems I have 2) or 3) [probably 2)!]. Now, I shouldn't have to remove the cup and cone when I remove the radiator, but I can imagine that the cup and cone might become damaged in the process and develop a leak when I re-hang the radiator. I'd like to have a few spares handy.
Could anyone suggest an on-line supplier of good quality cup and cones? I've tried the usual suppliers (Screwfix, BES, Plumbworld etc.) and they either don't stock them or I'm searching for the wrong thing!
Any pointers appeciated.
