This lightweight, highly flexible and compressible two-layer hose is engineered for the safe discharge of aggressive chemical vapors, gases, dust, and non-abrasive fibers, offering outstanding resistance thanks to its inner PTFE film. In the standard version, the white PTFE layer complies with FDA requirements, making it ideal for food industry applications, while the antistatic EL version with a black conductive PTFE layer (R ≤10⁶ Ω) ensures safe use in environments with electrostatic risks. Its robust construction, reinforced with an external galvanized steel spiral, guarantees durability against vibrations, stretching, tearing, and impacts, while also providing excellent resistance to UV radiation, ozone, and aging. With a compressibility ratio of up to 1:6, the hose is easy to handle, transport, and install using bridge clamps (left-handed). Available in lengths from 2 to 10 meters and, from 80 mm diameter, also with stainless steel spiral reinforcement, it is a versatile solution for both chemical and food industry operations. Operating reliably in temperatures from -40°C to +80°C, this hose combines safety, flexibility, and long-lasting performance, making it the perfect choice for demanding industrial environments.
