Quick
Just connect the plug to the socket
and twist the "Safety Lock" forconnection. Connection by one person
is possible.

Cleaning
No tools are required. All parts canbe disassembled quickly. Small
number of parts makes cleaning
easy.

Corrosion resistant
Stainless steel (JIS SUS316L equivalent)
for the liquid contact parts, buffing(#400) to prevent propagation of variousbacteria (electro-plating available onrequest). Less deterioration due toexcellent corrosion-proof material.

Versatile
There are two types of end
configurations. Ferrule shape (ISO2852 standard) and welding shape(JIS G 3447 standard).

Effortless operation unique to Cuplas

Safety standards
The seal material conforms to article No.
3-D-3-(1) Rubber utensils (except nursingutensils) or Containers / Packages. It has
passed both material and elution tests
specified in the Food sanitation Act and thestandards for Food and Food additives(Notice No.370 of 1959 issued by theMinistry of Health and Welfare of Japan).
Also conforms to standard No. 21 CFR
177.2600 of the US Food and Drug
Administration (FDA).

Construction
No tools are required. Since
the O-ring is attached
beforehand, it will not drop off
during connection likeconventional fittings.

Safety - Safety Lock function By rotating the cam handle,
the "Safety Lock" is activated,
and the O-ring sticks tightly
to prevent fluid leakage.
Reliable design with noprotruding of O-ring intopiping.

Accessories - Dust Cap Dust cap for both plug andsocket (made of polyethylene).
Prevents contamination offoreign matter into piping
during separation.

"Hygienic CUPLA" was born to solve the various troubles of ferrule
joints at food manufacturing factories, ［It takes time to disassemble
and clean］［It takes time and effort to assemble piping］［Clamps workloose and leak］［Packing can easily dislodge and becomecontaminated］［Overtightening the clamp cuts the packing］. Nitto
Kohki's "Quick Connect Couplings", which is active in a wide variety ofindustries, will further expand its field of activity.

Speedy disconnection

You can connect by just inserting the plug tothe socket and twisting the "Safety Lock".
Efficient piping is realized with ease andwithout any special skill.

As a safety measure, the "Safety Lock" featureensures that there can be no unintentional
disconnection of the Cupla. By turning the camhandle, you can maintain the connected stateof the socket and plug.

Disconnection of plug and socket can be donewith ease. Can be disconnected by unlocking
the "Safety Lock" and turning the cam handle.
No special skills required.

Precautions to be taken when using Cuplas

Because of the structure of this product, dead space is generated when using.

Enlarged view of seal part
Plug / Socket

Connected state

PlugSocket

When installing the Cupla on the pipe
Connection and disconnection ofsocket and plug is enabled bysliding either the socket or plug tothe central axis of pipe. Whenconnecting the couplers to thepipe, ensure that there is at least
minimum moving distance (L) in
the axial direction.
Amount of sliding (L)More than 40 mm

Disconnection

Connection• Any residual fluid remaining in the passage will spill out on disconnection. Drain any residual fluid before disconnection to avoid
burns or injury to the skin when dangerous fluid such as chemical agent or high temperature fluid is used.
There is a dead space in the Cupla. Be careful that this may lead to the spread of bacteria.
• The Cupla can be easily disassembled for cleaning. The Cupla should be evaluated before use to determine the suitability with regard
to sanitation and safety. Especially when using O-rings of other brands than Nitto Kohki, be sure to evaluate the O-ring at your end.
• Do not use the Cupla continuously under any pressure exceeding the rated working pressure.This may cause leakage or damage.
• Use only within range of its rated temperature. May cause damage or deterioration to the sealing and leak if used otherwise. Also, do
not use continuously at the lowest or highest working temperature.
• The durability of the Cupla differs depending on the operating environment and conditions (pressure and temperature etc.). If
necessary, conduct performance evaluation test under your actual operating environment and conditions.
• Connection and disconnection of socket and plug is enabled by sliding either the socket or plug to the central axis of pipe. Whenconnecting the couplers to the pipe, ensure that there is at least minimum moving distance in the axial direction.
• The outer diameter and thickness of the pipe to be welded to the Cupla must conform to JIS G 3447.
• Malfunction caused by welding (directly or otherwise) is not included in the warranty.
• When powder is applied to the Cupla, static electricity may be generated. Please take countermeasure against this if required.
• When the Cupla remains connected for long periods of time, it may become difficult to disassemble.
In this case, do not forcefully turn the socket and plug to disconnect as this may damage the seal material and cause leakage.
• The O-ring and Lock plate ASSY are consumable items.
• See the following list as a replacement guide for the Lock plate ASSY.

1000 times• When the Lock plate ASSY is deformed, replace it with a new one regardless ofconnection/disconnection times.
• The durability of the O-ring differs depending on the operating environment and conditions(pressure and temperature etc.).
• Be sure to read the "Instruction Sheet" that comes with the product before use.
