This lightweight, gray, and exceptionally flexible hose is designed for reliable performance in air conditioning, ventilation, and heating systems. Made from durable polyester fabric coated with PVC and reinforced with a galvanized steel spiral, it offers outstanding resistance to stretching, vibrations, and impacts, ensuring long-lasting durability even in demanding environments. Its flame-retardant and chemically resistant properties make it a safe and versatile solution, while the high compressibility ratio of up to 1:6 allows for convenient handling, storage, and installation. Available in standard lengths from 2 to 10 meters, with options for other colors or stainless steel spirals (from 80 mm diameter), it can be tailored to specific project requirements. For applications requiring additional safety, the AS version in black provides antistatic protection (R ≤10⁹ Ω). Easy to mount on couplings with left-handed bridge clamps, this hose guarantees secure and efficient installation. Operating reliably in temperatures from -20°C to +70°C, it is the ideal choice for professionals seeking a robust, adaptable, and high-performance solution for modern HVAC systems.
