Product Name Notes
1.5 ~ 2 times higher flow. High flow type with "Airless valve shut-off" design. Compared with nitto s conventional 35mpa cuplas The flow volume is increased 1.5 to 2 times.
A single operation makes simultaneous connections for multiple lines that have a variety of different fluids and sizes. A special design minimizes air admixture in fluid lines upon connection. Compared...
Connects multiple lines simultaneously with a single operation for different fluids and sizes. Ideal for automated hydraulic or pneumatic cylinder operated systems that need to connect and disconnect several lines...
Flat contact face design reduces spill upon disconnection by less than half compared with that of conventional design. Flat contact face design makes it easy to clean dust and foreign...
High flow type SP Cupla is now released! Plugs with male thread end are newly added.
Special steel body is tough against vibration and impact! Male and female thread end configurations are available. Low pressure loss characteristic suits hydraulic equipment applications. Quenched special steel body Powerful...
Stainless steel for excellent corrosion resistance! The unique “inner seal mechanism” accepts a working pressure up to 20.6mpa. Body material is excellent corrosion resistant stainless steel (sus304). Suited for use...
Their “airless valve shut-off design” greatly reduces air admixture! Ideal for hydraulic lines with larger pressure fluctuations. Locking mechanism to prevent accidental disconnection maintains tight connection even under vibration or...
Valveless structure suits high viscosity fluids! Various body materials, sizes and end configurations. Braided hose connection types are newly added. Valveless construction drastically saves pressure loss and achieves high flow...
