Brake line size?

[charlesmc]

I want to order 5052 tubing for our brake lines, but I'm away from the hangar for a while and wanted to double check which size to purchase. I have searched, but could not find the exact size in VAF. In section 5, it says that brake lines are 1/4, but I was not clear if that was ID or OD (OD I assume).

Grainger has 6' lengths of 5052 for $29 with no shipping costs if you pick it up. Grainger is five minutes away from me.

I'm looking at the 1/4in. x 0.035 thk.

Van's brake line tubing measurement is OD. More specifically, all tubing sizes are spec'd by OD.

.035 wall is fine
