E.J. Beverage Ultra Barrier Silver beer tubing is 100% PVC free, antimicrobial beer tubing that is more flexible than the rather rigid Bev-Seal glass lined tubing. This 3/16" interior diameter is perfect for beer lines of 6' or shorter. Pressure up to 40 psi. 7/16" outer diameter. Sold by the foot.
This tubing has 2.2 pounds of resistance per foot. What does this mean? It means if you have a 4' beer line of this tubing, you have a total of 8.8 pounds of resistance in the line. Generally, this means setting your PSI on your regulator to the same 8 PSI figure will result in good beer flow, although setting it lower (say 6 PSI or so) in some instances might be preferable to avoid adding carbonation to beer sitting in a keg.
