<VV> O-ring sizes for gas lines

[Derek Archer]

I found in the CORSA tech guide a (wonderful and intelligent) idea for 
using Viton o-rings in gas line flare connections to prevent leaks, a 
particular problem on our 'Vairs unless the flares are absolutely 
perfectly aligned in the connector. Anyway, at my local FLAPS I can 
only buy them in an assortment of sizes with only one size of about 12 
that fits. Does anyone else who does this know what size o-rings fit so 
I can order them from a supplier? IE -034, -111, etc.
