For Charging Industrial Gases and Refrigerants

Charge Cupla CS TypeFrequent connection and disconnection underpressure can be easily made with the uniquelever operation. Perfect for charging
refrigerant, vacuum suction, and discharging
residual pressure.

A general rule for identification• A Charge Cupla with CR seal :The body and grip are coated with blue
colored anodic oxidized alumina.
• A Charge Cupla with HNBR seal :The body and grip are coated with redcolored anodic oxidized alumina.
• Please contact us should you require anyother color.

• Equipped with an automatic shut-off valve. Fluid in the passage
is prevented from flowing out when disconnected.
• The Charge Cupla and Plug can be connected or disconnectedeven when the residual pressure remains. The shut-off valve
can be opened or closed with the lever on the back end.
• The safety design prevents the valve from opening even if the lever isoperated without connecting to the plug.
• The lever can be set to any position within the 360 degrees.
• The CS type can be connected to the standard 2P-V and 3-PV Plugs.
The CS-GN type is also available for the 2P-V-GN and 3P-V-GN Plugs on request.
• Hydrogenated nitrile rubber (HNBR) is colored in blue for easy recognition.
• The Charge Cupla that employs a double O-Ring seal structure for highairtightness is also available on request.

How to UseConnection to Plug
Pull the sleeve lever and push in the plug for connection.
Raising the lever on the back end to 90° L-shape opens
the shut-off valves of the Charge Cupla and Plug to allow
the fluid to flow.

Airless Charge Cupla

CNA Type

The Airless valve structure minimizes air
ingress on connection and fluid spillage ondisconnection. Perfect for charging refrigerant,
vacuum suction, and connection/disconnection
under residual pressure.
• A special airless valve structure is employed in both socket and plug. This
minimizes air ingress on connection and fluid spillage on disconnection.
(CNA-GN Type is also available on request.)• The Airless Charge Cupla and Plug can be connected or disconnected evenwhen the residual pressure remains. The airless shut-off valve can be opened
or closed with the lever on the back.
• The safety design prevents the valve from opening even if the lever isoperated without connecting to the plug.
