For improved safety and reliability
Piping changes within required lead time increase the probability of connection errors and impair the
safety of the work area. Multi Cupla removes the possibility of connection errors in multiple pipe
connection systems by its own design and by the connection system it is constructed on. Safety and
reliability in piping works can be enhanced further with the introduction of remote-control operation.

of fluid on disconnection.
Body materials other than stainless steel are available, which can be
ordered with or without valves. (Made-to-order products)
Snap-ring and screw thread-in types to mount on the base plate are
standardized.
MAS type can accept axial eccentricity of socket and plug, or allow a
plate hole position tolerance of 0.3mm because of the O-ring around
the body.

Minimal air admixture during Cupla connection
• Special valve structure allows minimal air admixture in fluid lines during Cupla connection.
• Liquid bleeding on Cuplas disconnection is very little, which makes it best for frequent connection/
disconnection applications.
• Snap-ring and thread screw mount types to mount on the base plate are standard.
• MALS type can accept axial eccentricity of socket and plug, or allow a plate hole position tolerance of
0.3mm because of the O-ring around the body.

Interchangeability
Socket and plug in the same size can be connected regardless of their end configurations.
A single operation makes simultaneous
connections for multiple lines that have
a variety of different fluids and sizes.
A special design minimizes air admixture
in fluid lines upon connection.
Compared with conventional Multi Cuplas, approximately double flow
rates are realized. This could reduce the size of required plates.
(Rate of flow increase depends on Cupla sizes.)
The MALC type realizes a 2mm axial eccentricity allowance, while the
conventional Multi Cupla is only 0.6mm.
Special valve design enables connection of socket and plug under
dynamic pressure of up to 2MPa.
When connected, the distance between the socket plate and the plug
plate is designed to be 30mm for all sizes. This means that any size of
Cupla can be mounted and used on the same plate.
Airless structure valves prevent outflow of fluid and admixture of air
into the fluid line.

Interchangeability
Socket and plug in the same size can be connected regardless of their end configurations.
A single operation makes simultaneous
connections for multiple lines that have
a variety of different fluids and sizes.
A special design minimizes air admixture
in fluid lines upon connection.
Compared with conventional Multi Cuplas, approximately double flow
rates are realized. This could reduce the size of required plates.
(Rate of flow increase depends on Cupla sizes.)
The MALC type realizes a 2mm axial eccentricity allowance, while the
conventional Multi Cupla is only 0.6mm.
Special valve design enables connection of socket and plug under
dynamic pressure of up to 8MPa.
When connected, the distance between the socket plate and plug plate
is designed to be 30mm for all sizes. This means any size of Cupla can
be mounted and used on the same plate.
Airless structure valves prevent outflow of fluid and admixture of air
into the fluid line.
Autocatalytic Nickel-Phosphorus coating is adopted for surface
treatment over special steel body and internal
parts. This coating is environment-friendly.

MULTI CUPLA Series
Nitto Kohki's depth of unique technologies and dedicated
research has been proven by numerous patents, which led to the
development of 25,000 different Cupla variations.
Applications diversify from general household to high-tech industries such as in oceanic and space development.
Diameters range from a tiny 1mm to a huge 540mm.
Wide varieties of body materials such as steel, brass, plastic, aluminum or stainless steel are availble.
Safety Guide
When selecting a suitable model of Multi Cupla, be sure to read each of the following precautions relating to the use of Multi Cuplas.
Overall Multi Cuplas
MAS Type / MAT Type
Warning
Warning
• Do not use couplings continuously under any pressure exceeding the rated working pressure.
• Do not use at temperatures outside the rated working temperature range. Otherwise you may damage the seal packing
inside and cause leakage.
• Do not disassemble.
• Do not connect /disconnect with fluid under dynamic pressure.
• The sides of hexagon shaped body parts on socket and plug should contact each other when the connection is complete.
• Never use socket & plug set that has an axial eccentricity of more than 0.6mm diameter range. This may cause leakage
or breakage.
Caution
Caution
• Do not tighten up the screw on Cupla exceeding the rated maximum tightening torque.
This may cause damage to the Cupla.
• Do not apply any artificial impact, bend, or tension other than necessary in connection and disconnection. This may
cause leakage or damage.
• Do not use in a place where metal debris or sands may be around. This may cause malfunction or leakage.
• Do not use for the purposes other than quick connective coupling between fluid pipelines.
• Direct hookup to a vibration or impact device may result in reduced lifetime of the Cupla.
• Fluid must be cleaned through filters before reaching the Cuplas.
• Do not strike the revealed end of an automatic shut-off valve with tools, such as a hammer. It may cause leakage or malfunction.
• Design and keep the fluid flow speed through Cuplas below 8 m/s.
• A shut-off valve must be installed between pressure source and the Cupla.
• Do not connect with other brands’ quick connective couplings.
• Inspect Cuplas periodically for wear. If any wear or defective area is apparent, discontinue use until repaired or replaced.
MAM Type
• Connection between the same MAT types is virtually not possible because there is no allowance for eccentricity.
• O-rings in Cuplas must remain lubricated at all times.
MALC-SP Type
Danger
• Do not pressurize the socket or plug with fluid of 2MPa or more. The valve may be blown out.
Warning
• Never use socket & plug set that has an axial eccentricity of more than 2mm diameter range. This may cause leakage
or breakage.
• Obliquity (misalignment) of socket and plug must be within 0.5 degrees during connection or disconnection; otherwise
this may cause leakage or breakage.
Caution
Warning
• O-rings in Cuplas must remain lubricated at all times.
• Do not drop Multi Cuplas. This may cause deformation of the plate.
Caution
MALC-HSP Type
• Always connect socket and plug after confirming the lever is in the “open” position in accordance with the instruction
booklet that comes with the products.
• The lever should not be turned by force. This may cause lever breakage.
• The number of hoses and the position of the hoses to be connected to the Cupla should be arranged symmetrically from
the lock part so as to distribute and control the reaction evenly.
• Apply seal packing liquid/tape on male taper threads to ensure no leak.
• Packing seals in Cuplas must remain lubricated at all times.
MAM-B Type / MAM-A Type
Danger
• Do not pressurize the socket or plug with fluid of 8MPa or more. The valve may be blown out.
Warning
• Never use socket & plug set that has an axial eccentricity of more than 2mm diameter range. This may cause leakage
or breakage.
• Obliquity (misalignment) of socket and plug must be within 0.5 degrees during connection or disconnection; otherwise
this may cause leakage or breakage.
Caution
Warning
• Do not connect or disconnect the Cuplas under a dynamic or residual pressure of 0.6MPa or more. This could lead to
Cupla damage.
• Do not drop Multi Cuplas. This may cause deformation of the plate.
• O-rings in Cuplas must remain lubricated at all times.
Caution
• Always connect socket and plug after confirming the lever is in the “open” position in accordance with the instruction
booklet that comes with the products.
• The lever should not be turned by force. This may cause lever breakage.
• When replacing a Cupla from a plate, carefully remove the C-type retaining rings by using a C-ring remover tool. Use caution
not to over expand the C-ring. It is recommended, however, that a new C-type retaining ring is used when a Cupla is replaced.
• The number of hoses and the position of the hoses to be connected to the Cupla should be arranged symmetrically from
the lock part so as to distribute and control the reaction evenly.
• Packing seals in Cuplas must remain lubricated at all times.
Specifications and designs are subject to change at any time without notice.
