In systems that demand both reliable fluid transfer and a clean, sanitary appearance, flexible stainless steel hoses often outperform rigid pipe. The 201 SS Polishing Hose from NUHU is engineered for installers, maintenance teams, and equipment manufacturers who need a polished stainless steel connector that resists corrosion, handles vibration, and fits into compact layouts. Below you will find a complete technical profile, product parameters in list and table formats, and practical answers to common questions about this hose style. This series includes products such as 1.5–1.7m Extendable Flexible Stainless Steel Hose, etc.
The 201 SS polishing hose consists of an annular corrugated inner core made from grade 201 stainless steel, covered by a braided outer sleeve of the same material. The outer sleeve receives a mechanical polishing treatment that removes surface oxidation, weld discoloration, and minor scratches. This polishing process creates a smooth, reflective finish that is easier to clean and visually consistent. NUHU manufactures the hose using ISO-certified welding and forming processes. Each assembly is tested for leaks before packaging.
Grade 201 stainless steel contains chromium, nickel, and manganese. It provides good strength and moderate corrosion resistance. For applications involving mild acids, alkaline cleaning agents, or humid environments, the material performs well when the surface is maintained. The polished finish helps reduce the buildup of contaminants and supports sanitation routines in food, beverage, and pharmaceutical environments.
The polished outer braid of the 201 SS polishing hose resists dirt accumulation, but regular cleaning is still recommended in sanitary environments. Use a soft cloth or sponge with warm water and a mild detergent. Avoid chlorinated cleaners or abrasive pads that could scratch the surface or damage the passive oxide layer. After cleaning, rinse with clean water and dry the surface to prevent water spots. If the hose is used in a clean-in-place system, ensure that the cleaning chemicals and temperatures fall within the specified limits. For interior cleaning, NUHU can supply hoses with an electropolished inner core to facilitate flushing and reduce microbial adhesion.
