Flow Direction• Both socket and plug have built-in automatic shut-off valves.
• High flow rate type to increase cooling effect.
• Quick connection and disconnection of cooling pipes.
• Compact and space-saving design. Compared with the coupled length ofSP Cupla type A, that of High Flow Cupla is reduced by 22%.
• Installation and maintenance can be done within a short time.

Fluid flow can be bi-directional whensocket and plug are connected.

Interchangeability
Different sized sockets and plugs cannot be connected to each other.

Flow Direction
Fluid flow can be bi-directional whensocket and plug are connected.

High flow Cupla and ferrule flange are
combined to achieve efficient piping.
• Easy connection with stainless steel pipe.
• Connection to plastic hose is possible with optional hose connection kit.
• Connection to various tubes is also possible via the use of appropriate
optional inserts.

Interchangeability
Different sizes are not connectable.
