Double-walled EVABarrier tubing for tidy, efficient draft setups. The smaller 3 mm internal diameter cuts excess beer-line length and clutter, while the double-wall construction gives excellent gas retention and oxygen protection — so beer stays carbonated and fresh in the line. Pairs with 6.35 mm Duotight or John Guest push-fit fittings.
