Flexible suction hose supplied as a ready-made pipe, with mounted fittings, clamp, and rope, intended for sewage and water. Externally corrugated, almost smooth on the inside. The special profile makes the hose resistant to vacuum and kinking (returns to its shape). As a polyethylene hose, it has very good chemical resistance and resistance to biological corrosion (rotting, decay). It is flexible at low temperatures. Short sections of hose, 1 m in length with fittings, are used as protective hoses, resting on the edge of the channel opening, inside which a pressure cleaning hose or inspection hose with a camera is introduced. The clamp mounted on the fitting with an attached 7.5 m rope allows for maintaining the proper position of the protective hose. Length: 1 m. Hose material: yellow polyethylene profile (PE). Reinforcement: black polyethylene profile (PE). Vacuum: 0.95 bar. Operating temperature: from -40°C to +60°C.
