Quick connect coupling F35 Cupla F35-2S, steel - Nitto Kohki 439828309

On hydraulic attachments used outdoors, dirt collects exactly where the coupling is made, and every drop of oil on the ground is a problem. The Flat Face Cupla F35 has flat contact faces that can be wiped clean and works at 35.0 MPa in port sizes 1/4 inch to 1 inch.

• Working pressure of 35.0 MPa in port sizes 1/4 inch to 1 inch, matched to high pressure hydraulics on attachments and machines.
• The flat contact face design cuts spillage on disconnection to less than half of a conventional design, which reduces oil loss and contamination on site.
• Dust and foreign matter can be wiped off the flat face before connection, so they do not get inside and cause faulty connection or disconnection.
• Air admixture on connection of only 0.1 mL on F35-2SP and F35-3SP up to 0.4 mL on F35-8SP, so very few air bubbles enter the hydraulic line.
• Push-to-connect operation, with the sleeve stopper engaged afterwards by rotating the sleeve, which holds the connection under vibration and impact.
• Minimum cross-sectional area from 34.2 mm2 on F35-3SP up to 227.0 mm2 on F35-8SP with considerably reduced pressure loss, suited to applications that need big flow.
• 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.

Technical data

Applications

• Hydraulic attachments used outdoors, for example on snow plows
• Hydraulic circuits up to 35.0 MPa with frequent tool or implement changes
• Dusty and dirty environments where the contact face has to be cleaned before coupling
• Applications where escaping hydraulic oil would contaminate the ground or the workpiece
• High flow lines that require low pressure loss across the coupling

Compatibility

Different sizes cannot be connected to each other. Connect and disconnect only when the line is free of pressure, never while pressure is applied or remaining. The F35 Cupla is not suitable for vacuum applications in either connected or disconnected condition.
