Where to buy longer airline for Doc 9004?

[necessary_evil]

I need to extend the airline on my 9004 a bit due to new tank setup. Any recommendations? I can't seem to find the same diameter and flexibility at my LFS.

We do sell it and it is just commercial grade silicon airline, it is our part 7072.200

Really with a coupler and any airline tubing you could extend it.

Great thank you. What is the ID/OD of the tubing

It is just heavy walled airline tubing, 4mmID, 6mm OD, you can use ordinary silicon airline, it just has a thinner wall, the common stuff has a 1mm wall, ours has a 1.5mm wall and it is not anything custom or proprietary it is what is used for CO2 or heavy duty applications.
