Help needed re o-ring on oil pipe

Hi
Can anyone who has done the disco 200tdi conversion possibly help with info on the o-rings found at the radiator end of the oil cooling pipes?
I think i may have lost one whilst replacing the radiator or at least there is only one left on one pipe end!!!
can't seem to see any refference in parts manual.

Cant seem to find one too , your best bet is to go to your local garage or motor factors with the one you have , cost u pence .
