Quick connect coupling Micro Cupla MC-04PC, 4 mm, brass - Nitto Kohki 590610410

Pneumatic control equipment rarely leaves room for full size couplings around cylinders and valves. Micro Cupla keeps the sleeve outer diameter down to 9.5 mm, works at 1.0 MPa and is connected by pushing the plug in by hand.

• Sleeve outer diameter of 9.5 mm even though the shut-off valve sits inside the socket, so the coupling still fits tight tubing runs.
• Working pressure of 1.0 MPa (10 kgf/cm2) for air and water, with the Tube Fitter version not suitable for water.
• Rated for vacuum service down to 53.0 kPa (400 mmHg), tested with air at room temperature.
• One-way shut-off with the valve in the socket, and when coupled air flows in either direction from the plug or the socket side.
• Bodies in plated brass or SUS 304 stainless steel for good corrosion resistance, with the Tube Fitter in chrome-plated brass.
• Nitrile rubber NBR seals cover -20 to +80 °C, fluoro rubber FKM for -20 to +180 °C is available as a made-to-order item.

Technical data

Applications

• Tubing inside pneumatic control devices where space is limited
• Connections to air cylinders and solenoid valves
• Vacuum lines down to 53.0 kPa (400 mmHg)
• Low pressure water lines up to 1.0 MPa, without the Tube Fitter end
• Panel mounted socket installations in control cabinets

Compatibility

Sockets and plugs of the Micro Cupla range connect regardless of the end configuration, only the series has to match. Fluid escapes from the plug side on disconnection, so take the necessary precautions when the medium is water.

Standards and compliance

Thread ends are M5 x 0.8 with a maximum tightening torque of 1.3 Nm and 1/8 inch with 7 Nm, and the materials used are SUS 304 stainless steel, plated brass, nitrile rubber (NBR) and fluoro rubber (FKM).
