Co2 Tubing

[GUB]

Looking for a source of co2 tubing, but this seems tricky to find (have tried google and my usual aquaria suppliers, can't remember ever seeing any in LFS). Could someone share a link (or PM me one) to a good supplier please? Thanks

Edit: UK based preferably!

Just found that Fish, Fur and Feather sell it too:

They do black and clear by the looks of it.

Can anyone tell me though, when you see air tubing/Co2 tubing advertised as 4mm and 6mm, is that the internal or external diametre?

I would think external, though if you just want Co2 'proof' airline tubing, silicone tubing is said to be a good choice,

6mm external, 4mm internal.

Regular silcone airline will fit but leaks CO2 though the tube walls.

Ahh, oh well, somewhere gave me poor advice! Is it a major enough issue for yeast-based CO2? I only have ~6 inches of silicone line that than hits a t-peice then onto CO2 tubing to the diffusor.
