Lightweight, highly flexible and bendable, chemically and thermally resistant two-layer hose designed for the discharge and transfer of the most chemically aggressive vapors, gases, dust, and fibers (non-abrasive), as well as for the blowing of hot air. Very good chemical resistance to aggressive chemicals due to the internal layer of PTFE. In the standard version, the internal layer of white natural PTFE meets food industry requirements (FDA). In the antistatic version EL, the black internal layer of PTFE is electrically conductive (R ≤10⁶ Ω). The hose features high compressibility – up to 1:6, a strong construction resistant to vibrations, stretching, and tearing, and impact resistance due to the external spiral. Resistant to UV radiation, ozone, and aging. Used in the chemical, petrochemical, and food industries. Also available with a stainless steel spiral (from a diameter of 80 mm). Hose installation on couplings with bridge clamps (left-handed). Chemical resistance verification – chemical resistance table for PTFE (preliminary selection), confirmation of resistance and application conditions – by Tubes International. Standard length: from 2 to 10 m. Hose material internal layer: white PTFE film – standard version HYTEF, black conductive PTFE film – antistatic version HYTEF EL. Hose material external layer: black polyethylene fabric coated with CSM rubber. Reinforcement: external spiral made of galvanized steel wire and sheet. Operating temperature: from -35°C to +175°C (temporarily up to +190°C).
