Lightweight, highly flexible and bendable, temperature-resistant two-layer suction and discharge hose designed for the removal and transfer of vapors, fumes, and high-temperature air. Flame-retardant, chemically resistant, with fairly good resistance to hot sparks. Used in the construction of furnaces (metal and glass foundries, ceramic and chemical industries), vehicles (exhaust gas discharge systems, engine testing stations, etc.), aerospace and military applications. Characterized by high compressibility – up to 1:6, strong construction, and impact resistance due to the external spiral. Also available with a stainless steel spiral (from a diameter of 80 mm). Hose installation on couplings with bridge clamps (left-handed). Standard length: from 2 to 10 m – contact Tubes International. Hose material: 2 layers of glass fabric, with the outer layer coated in silicone (gray). Reinforcement: external spiral made of galvanized steel wire and sheet. Operating temperature: from -50°C to +450°C (temporarily up to +500°C).
