Silicone hose 6,0 x 2mm. (per meter)
inside dimension: 6.0mm
material thickness: 2mm
outside diameter: 6.0+(2*2)= 10.0mm
The big advantage compared to the other hoses is that these silicone hoses remain flexible even after years and have a sound dampening effect, the resonance that pumps can produce are absorbed by the hose.
