Barriermaster™ Flavourlock Beer Trunk Lines

The next step in flavor protection. Micro Matic, the industry leader introduces the next generation of beverage tubing. Barriermaster Flavourlock™, standard in all our trunkline, is engineered to have an exceptional gas barrier layer along with outstanding hygienic quality. Independent testing and in-field performance have found Barriermaster™ Flavourlock superior. A barrier layer is co-extruded within the tube wall to stop gas permeation and preserve the beverage aroma and flavor.

The patented Barriermaster Flavourlock™ beer line tubing and Black Diamond® Jacket provide optimal beverage integrity and quality, with exceptional thermal performance—delivering excellent return-on-investment and an overall great draft experience.
