Radiators smaller then tail size

[Livvid]

Hi all, what's a good solution for fitting a radiator which is slightly smaller than the one that came out, is there a nice fitting that tails out of the radiator into a section of 15mm?!!!!
I came across some fitted by British Gas, real chunky connectors but they look too much for the job.

You can buy valve extension tails from any plumbers merchants. Available in different lengths and types. 10mm,20,30,40mm etc also adjustable tails for valves with 3/4" nuts.
