This is a heavy walled tubing and has the proper inside
dimension for serving your beer.
The additional thickness helps keep
your dissolved gas in your beer and prevents your tubing expanding
because of pressure in your beer.
The beer will lose ½ pound of pressure
per foot of tubing as well as ½ pound pressure of vertical lift.
recommend a length of tubing between 5 feet and 8 feet with your
pressure gauge set between 8 and 12 PSI on your gauge.
