2 MULI CUPLA Series Multi Cupla MAM ype Simultaneously connects multiple lines for different fluids and sizes with a single operation. NEW Multi Cupla MAM-B ype NEW Contributes to increase work efficiency, to secure reliability and safety, to improve productivity, and to reduce cost. Excellent assistance in building automation and/or unmanned systems for machines that need quick replacement, connection/disconnection, transfer, and/or inspection. Minimizes setup time. Downsizes the plate for multiple piping. Prevents possible human errors in piping jobs. Multi Cupla MAM-A ype Multi Cupla MAS ype / MA ype Multi Cupla MALS ype / MAL ype Multi Cupla MALC ype 1

3 MULI CUPLA Series For improved productivity and realization of FMS (Flexible Manufacturing System) Multi Cupla minimizes the setup time of piping connection jobs in mold changes, which enhances productivity, and realizes the Flexible Manufacturing System. his is especially important as manufacturing a wide variety of products necessitates frequent mold changes and setups.

MAM-B ype For multiple and simultaneous air/water piping ports type (: 1/4") 8 ports type (: 1/8" 1/4") 1 ports type (: 1/8") Page -8 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.

Compared with conventional Multi Cuplas, approximately double flow rates are realized. his could reduce the size of required plates. (Rate of flow increase depends on Cupla sizes.) he MALC type realizes a mm axial eccentricity allowance, while the conventional Multi Cupla is only 0.mm. Special valve design enables connection of socket and plug under dynamic pressure of up to MPa. When connected, the distance between the socket plate and the plug plate is designed to be mm for all sizes. his means that any size of Cupla can be mounted and used on the same plate.

A special design minimizes air admixture in fluid lines upon connection. Compared with conventional Multi Cuplas, approximately double flow rates are realized. his could reduce the size of required plates. (Rate of flow increase depends on Cupla sizes.) he MALC type realizes a mm axial eccentricity allowance, while the conventional Multi Cupla is only 0.mm. 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 mm for all sizes. his 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. his coating is environment-friendly.

20 MULI CUPLA Series Nitto Kohki's depth of unique technologies and dedicated research has been proven by numerous patents, which led to the development of 5,000 different Cupla variations. s diversify from general household to high-tech industries such as in oceanic and space development. Diameters range from a tiny 1mm to a huge 5mm. 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 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. Caution Do not tighten up the screw on Cupla exceeding the rated maximum tightening torque. his may cause damage to the Cupla. Do not apply any artificial impact, bend, or tension other than necessary in connection and disconnection. his may cause leakage or damage. Do not use in a place where metal debris or sands may be around. his 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 ype Warning Do not drop Multi Cuplas. his may cause deformation of the plate. 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. he lever should not be turned by force. his may cause lever breakage. he 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 ype / MAM-A ype Warning Do not connect or disconnect the Cuplas under a dynamic or residual pressure of 0.MPa or more. his could lead to Cupla damage. Do not drop Multi Cuplas. his may cause deformation of the plate. 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. he lever should not be turned by force. his 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. he 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. MAS ype / MA ype Warning Do not connect /disconnect with fluid under dynamic pressure. he 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.mm diameter range. his may cause leakage or breakage. Caution Connection between the same MA types is virtually not possible because there is no allowance for eccentricity. O-rings in Cuplas must remain lubricated at all times. MALC-SP ype Danger Do not pressurize the socket or plug with fluid of MPa or more. he valve may be blown out. Warning Never use socket & plug set that has an axial eccentricity of more than mm diameter range. his 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 O-rings in Cuplas must remain lubricated at all times. MALC-HSP ype Danger Do not pressurize the socket or plug with fluid of 8MPa or more. he valve may be blown out. Warning Never use socket & plug set that has an axial eccentricity of more than mm diameter range. his 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 O-rings in Cuplas must remain lubricated at all times. Specifications and designs are subject to change at any time without notice.
