This lightweight, highly flexible, and flame-retardant hose is engineered for demanding applications in air conditioning, ventilation, and heating systems, ensuring safe and efficient extraction and transfer of hot air, exhaust gases, and chemically aggressive vapors. Manufactured from durable black polyester fabric coated with CSM (Hypalon) and reinforced with a robust external galvanized steel spiral, it offers exceptional resistance to UV, ozone, weathering, vibrations, stretching, and impacts. Its outstanding compressibility ratio of up to 1:6 allows for easy handling, storage, and installation, while the left-handed bridge clamp mounting ensures secure coupling. Designed to perform reliably in extreme environments, it operates within a wide temperature range from -35°C to +175°C, withstanding peaks up to +190°C. Available in standard lengths from 2 to 10 meters and optionally equipped with a stainless steel spiral from 80 mm diameter upwards, this hose is the perfect solution for vehicle equipment, engine compartments, and the chemical industry. For precise chemical resistance verification, reference to the CSM resistance table and consultation with Tubes International is recommended, guaranteeing optimal performance tailored to specific operating conditions.
