The inner layer is made of smooth synthetic rubber, resistant to sludge and sewage. The corrugated outer layer provides a small bending radius and is resistant to ozone, weather conditions, and aging. Intended for agricultural, construction, and industrial applications, used for emptying septic tanks, as a suction hose for water and sewage pumps, for drainage and irrigation, and for tankers. Can be used for air extraction, dust, and bulk materials. Installation – depending on the diameter and type of fittings using steel bands, clamps, brackets, or compression sleeves. Inner layer: black synthetic rubber (SBR). Reinforcement: synthetic cord, steel spiral. Outer layer: black corrugated synthetic rubber. Working pressure: 3 bar. Operating temperature: from -30°C to +70°C.
