Flexo-ExGas gas hoses have a densely arranged notch structure ensuring flexible and extensible connection of all fixed gas domestic appliances to the gas installation. The surface of the corrugated stainless steel hose is covered with a protective layer made of polyolefin. Connection hoses are subjected to a special heat treatment, which eliminates the stresses caused by mechanical treatment and the process of fixing the connections. Thus increasing the flexibility and corrosion resistance, while reducing their stiffness. Heat treatment preserves the designed shape of our flexible and extensible gas hoses. The products are covered by a 10-year warranty.
