Bevlex tubing is a high quality thick-walled tubing. This 3/16" tubing works well for beer line, as it is the standard inner diameter for most serving systems. While the thinner walled tubing may also be used, this thick-walled tubing is recommended for permanent installations, such as on a kegerator or keezer dispensing system. It is also recommended when a thicker wall would come in useful. It is more durable and can withstand more pressure than the thinner-walled version.

Inner Diameter: 3/16 in.
Outer Diameter: 7/16 in.
