This EVABarrier hose is very suitable to use with the fittings that can be found under 'accessories'. The hose has an inner diameter of 6 mm and an outer diameter of 9.5 mm.
EVABarrier hoses are known for their high quality and solid double wall. Their impenetrable walls prevent liquids/gases from leaking, so your beer stays fresh longer and does not oxidise in the pipes. The smooth internal surface makes it difficult for bacteria and microbes to cling to.
