EVA Barrier 4mm ID x 8mm OD Double Wall Black Tubing (sold per metre)

The outer barrier has accurately extruded tolerances and made from an EVA material. It also seals well when used with various John Guest, duotight or other push in fittings.  The outer barrier gives the tubing excellent kink resistance, so the line is able to bend around a tight radius without kinking.

Inner Barrier
The inner barrier is made from a proprietary polymer that has excellent gas barrier and now with LightShield technology an excellent UV and Visible light blocking properties.
The significantly better barrier properties means your beverage is better protected from oxygen and also has a better barrier to CO2 loss.  So, your beer will stay fresher for longer and not lose carbonation like other beer line types.  In some beer line types, you may notice that the beer sitting in the lines starts to taste flat and/or oxidised when sitting in the lines for an extended period.  EVABarrier tubing is significantly better in this regard, and you will notice a significantly improved freshness of your beer especially if it's been sitting in the lines.

Best of all, you will now be able to distinguish between beer and gas lines!
