Quick connect coupling S210 Cupla S210-8S, stainless steel - Nitto Kohki 590520811

Sea water, salt air and changing media wear out a hydraulic coupling faster than pressure alone. The S210 Cupla is made of SUS304 stainless steel and still reaches 20.6 MPa working pressure thanks to its inner seal mechanism, the same level as special steel bodied couplings.

• Working pressure of 20.6 MPa in port sizes 1/4 inch to 1 inch, achieved by the inner seal mechanism despite the stainless steel body.
• SUS304 stainless steel body with high corrosion resistance, made for tough conditions such as ocean development.
• Safety lock against accidental disconnection, engaged by pushing the sleeve stopper and turning it 90 degrees, which holds the connection under vibration and impact.
• Automatic shut-off valves in both socket and plug prevent fluid outflow on disconnection.
• Minimum cross-sectional area from 24 mm2 on S210-2SP up to 233 mm2 on S210-8SP, and once coupled the fluid may flow in either direction.
• Fluoro rubber FKM as the standard seal for -20 °C to +180 °C, nitrile rubber NBR for -20 °C to +80 °C as a made-to-order item, released for water, air, hydraulic oil and gas.
• A dust cap is supplied with the product and keeps the connecting face clean between uses.

Technical data

Applications

• Ocean development and offshore installations with a high corrosion load
• Hydraulic circuits up to 20.6 MPa in environments where plain steel corrodes too quickly
• Water and gas lines within the permitted media range
• Equipment exposed to vibration and impact, where the safety lock rules out disconnection
• Vacuum service down to 1.3 Pa, released for the coupled pair only and not for socket or plug on its own

Compatibility

Different sizes are not interchangeable, so a coupling always consists of a socket and a plug of the same size.

Standards and compliance

The body is made of SUS304 stainless steel, with fluoro rubber FKM and nitrile rubber NBR as the specified seal materials.
