Simultaneously connects severalports securely in one operation!
Greatly reduces changeover timein multiple ports replacement.
• Handles several ports at once.
• Simple manual lever action completes easy connection / disconnection.
• Two-stage lever operation prevents Cupla from accidental dropping
due to sudden detachment.
• Comes with lock mechanism to prevent accidental disconnection.
• Large flow equivalent to that of SP Cupla Type A.
• Two kinds of plates are available for each size.
• Automatic shut-off valves in both socket and plug prevent fluid spillout on disconnection.
• Self-aligned valve design provides safety sealing of individual socket or plug
when disconnected.
