Nitto Kohki

Nitto Kohki Nitto Kohki U.S.A., Inc. was founded in 1969 to provide sales and service of machine tools and quick disconnect fluid couplings. These products fulfill vital roles in fields ranging from applications in the construction industry and the automotive industry, to high-tech engineering.

Nitto Kohki produces couplings for many applications. Quick disconnect fluid couplings are extremely successful in die-casting operations due to long working life and consistent performance under harsh die-cast conditions. Specialty couplings are used for leak-test applications, ranging from hot engine, transmission, and power train to power steering and radiator systems. Injection molding fluid couplings maximize coolant flow rates to molding dies to reduce customer cycle time. Refrigeration applications couplings are ideal for holding negative pressure of vacuum in leak testing or refrigerant charging/filling processes.

The Nitto Kohki brand includes:

  • Quick Disconnect Fluid Couplings — offer hydraulic and pneumatic couplings for leak testing, die casting, injection molding, refrigeration and semiconductor applications.
  • Air compressors and vacuum pumps — offer a wide range of linear piston air compressors, vacuum pumps, blowers along with quiet AC/DC diaphragm pumps.
  • Electric Screwdrivers — Eco-friendly with built-in brushless motors in transformer-less profile.
  • Industrial tools — air/power tools, machine tools, cutters, and tool balancers.
