Fully Washable Coupler for Hygienic Applications – HYGIENIC CUPLA

Fully Washable Coupler for Hygienic Applications – HYGIENIC CUPLA

Tool-Free Assembly and Disassembly! Connect and disconnect with smart, effortless operation

The "HYGIENIC CUPLA" is a quick connect fluid coupling of the easy-wash type. No tools are required, allowing all parts to be quickly disassembled, and with fewer components, cleaning is simple. The connection operation involves linking the plug and socket and applying the "safety lock," enabling a single operator to make the connection. Additionally, stainless steel equivalent to "SUS316L" is used for the parts in contact with the fluid. It is processed with buffing (#400) to prevent bacterial growth (electropolishing available), which suppresses material degradation with superior corrosion resistance. Features: ■ Simple connection ■ Safety lock function ■ Quick separation ■ Efficiency during maintenance ■ Easy full wash ■ Meets strict safety standards For more details, please refer to the PDF document or feel free to contact us.
