the thing is that the fittings will vary - you happen to have some that match the nominal diimension, but others may not - the 3/8" BSP fittings on later LRWWs and the cascades for example are
considerably wider than that...
in teh thread i referred too a sample of different 1/4" BSP 1/2" OD barbs varied between 10MM
and 8.5MM
ID iirc .....
