Noble Gases and Vacuum Nitto Kohki

Nitto Kohki noble gas and vacuum fittings deliver leak-tight connections rated for operating pressures from full vacuum (0 mbar absolute) up to 20 bar, with residual leakage rates below 1 x 10^-6 mbar·l/s. One-touch coupling bodies are machined from stainless steel (SUS316) or brass, meeting the dimensional interchangeability requirements of ISO 6150 Class B, and seal reliably across a service temperature range of -10 to +150 °C without retooling.

As an authorised stocking distributor for Nitto Kohki pneumatic components, esd.equipment offers 95 products from the Edelgase und Vakuum range available for immediate dispatch. All coupling series conform to Nitto Kohki interchangeability standards and are referenced against DIN EN ISO 4414 (pneumatic fluid power - general rules) and applicable SEMI and IEC installation guidelines, providing a single verified source for specialist gas-handling and vacuum applications.

Typical application areas: Semiconductor fab gas distribution (SEMI S2, SEMI F57), laboratory and analytical instrument gas supply (ISO 10328, DIN EN ISO 4414), vacuum handling in SMT pick-and-place and reflow lines (IEC 61340-5-1), medical device manufacturing inert gas purging (ISO 13485), automotive paint shop and body-in-white pneumatic tooling (IATF 16949, VDA 6.3), and aerospace MRO purge and pressurisation rigs (AS9100).
