NORRES METAL HOSE INOX 378
Stainless steel hose for high-temperature and chemical applications
The NORRES METAL HOSE INOX 378 is a flexible and robust stainless-steel hose designed for the suction and discharge of gases, vapours, and liquids at high temperatures and under demanding industrial conditions.
Manufactured from high-quality AISI 304 stainless steel, it combines excellent temperature resistance, electrical conductivity, and mechanical strength for safe operation in ATEX-classified zones.
Technical note
The METAL HOSE INOX 378 provides maximum durability in environments where synthetic materials are not suitable.
It is resistant to temperature extremes, mechanical stress, and most solvents and oils.
Thanks to its electrically conductive metal design, it can be safely grounded in ATEX zone 21 / 22 installations to prevent static build-up.
Typical uses include chemical processing, ventilation, exhaust systems, and mechanical engineering.
