EVABarrier Double Wall Tubing (6 mm ID, 12 m Roll) is designed for draft dispensing applications. The inner barrier helps maintain CO₂ levels and prevents oxygen ingress, while the smooth inner wall minimizes buildup. The outer wall provides stiffness while remaining flexible, making the tubing kink-resistant and compatible with Duotight, John Guest, and other push-in fittings. Recommended for use as gas lines or long-draw beverage lines, with 20–25 ft. per line for optimal flow.
