This lightweight, highly flexible suction and discharge hose is engineered for demanding applications requiring durability, safety, and resistance to extreme conditions. Constructed from two layers of glass fabric with a silicone-coated outer surface, it offers outstanding performance in transferring vapors, fumes, and hot air, even in environments reaching up to +450°C (with short-term resistance up to +500°C). Its flame-retardant and chemically resistant design ensures reliable operation in industries such as metal and glass foundries, ceramics, chemicals, as well as in vehicle exhaust systems, engine testing stations, aerospace, and military sectors. The hose is reinforced with a robust external galvanized steel spiral, providing excellent impact resistance and high compressibility up to 1:6, making it easy to handle and store. For larger diameters (from 80 mm), a stainless steel spiral option is available to further enhance durability. Installation is quick and secure with bridge clamps (left-handed), while standard lengths range from 2 to 10 meters, tailored to diverse operational needs. Combining strength, flexibility, and superior resistance to sparks and heat, this hose is the ideal solution for professionals seeking long-lasting performance in the most challenging environments.
