is a medium-heavy, food-safe transport hose for abrasive solids, oil and petrol resistant, gas-tight, good chemical resistance, free of plasticizers and halogen, generally good UV and ozone resistance, light, extremely flexible, smallest bending radii, high tensile and tear strength, largely smooth inside and optimal flow properties. Conductive (according to BGR 132, formerly ZH 1/200) when the stainless steel spiral is grounded.
