Coolant change hose diameters

[barker22]

Hey guys
Just wondering if anyone knows the diameter of the lower/top rad hose and the expansion tank hoses.
Doing a coolant change tomorrow and just need to get some jubilee clips to replace the renault clips.
Cheers

Top Coolant Bottle Hose - 12-22, Pt No 77 03 083 462 £1.70+vat

Bottom Coolant Bottle Hose - 16-27, Pt No 77 03 083 477 £1.70+vat

Top Rad Hose - 30-45, Pt No 77 03 083 430 £1.70+vat

Im guessing that 12-22, 16-27 & 30-45 are the sizes as thats the numbers in the description.
