But I found that the seal on my radiator's 1/2" barbs doesnt fit properly and there was a very very slight leak, possibly the cause of my random windows corrupt, but a) I dont think so, and b) it best not be

So can anyone tell me where to get these from/start looking for them:
AS568A-112 rubber 'o' rings (Basically 1/2" or 12mm ID).
(It doesnt help that I'm in the UK and thats an American standard!)
But I was wondering if anyone knows where I can get hold of either those, or a swiftech 'spares kit' with some of those in along with some proper swiftch 1/2" barbs to screw fittings (I think the ones I am using atm are G14(??) or some plumbing standard and as such are not tight enough.)
Many Thanks,
Dan
