Quick connect coupling Nut Cupla 65SN, steel - Nitto Kohki 313102340

On an air line every second lost during a tool change counts. Nut Cupla runs at 1.5 MPa working pressure with one-way shut-off in the socket, and the 200 series versions are coupled by simply pushing the plug in.

• Working pressure of 1.5 MPa (15 kgf/cm2) for compressed air, with a chrome-plated steel body.
• One-way shut-off with the valve in the socket, which is why the fluid has to run from socket to plug.
• The 200 series versions connect without pulling back the sleeve, which cuts connection time.
• A revised valve design lowers pressure loss and raises flow rate by 15 percent over the previous model.
• End-face seal when coupled instead of an external O-ring, so exhausted lubrication cannot damage the seal.
• Nitrile rubber NBR seal for -20 to +60 °C, intended for air rather than water or oil.

Technical data

Applications

• Compressed air lines in production and assembly
• Connecting pneumatic tools that are changed often
• Miniature pneumatic equipment and automatic control equipment
• Physicochemical equipment and laboratory rigs
• Air supply on medical devices

Compatibility

The coupling is interchangeable with Hi Cupla models 20, 30 and 40 and with the corresponding models of the Hi Cupla series. Fluid must run from socket to plug, and the range is not suitable for vacuum service in either the connected or the disconnected condition.

Standards and compliance

Thread ends are supplied in 1/4, 3/8 and 1/2 inch as R male and Rc female threads, maximum tightening torques are 14 Nm, 22 Nm and 60 Nm, and the materials used are chrome-plated steel and nitrile rubber (NBR).
