Operating principle
- Handles several ports at once.
- Simple manual lever action completes easy connection/disconnection.
- Two-stage lever operation prevents CUPLA from accidental dropping due to sudden detachment.
- Comes with lock mechanism to prevent accidental disconnection.
- Large flow equivalent to that of SP CUPLA Type A.
- Two kinds of plates are available for each size.
- Automatic shut-off valves in both socket and plug prevent fluid spill out on disconnection.
- Self-aligned valve design provides safety sealing of individual socket or plug when disconnected.

| Series | Max working pressure | Size range | Valve structure | Applicable fluids |
|---|---|---|---|---|
| MULTI CUPLA MALC Type | MALC-01 Type: 1.0 MPa {10 kgf/cm2}; MALC-SP Type: 1.5 to 7.0 | MALC-01 Type: one size; MALC-SP Type: sizes 1, 2, 3, 4, 6, 8 and 12; MALC-HSP Type: sizes 1, 2, 3, 4, 6 and 8 | MALC-01 Type: One-way shut-off; MALC-SP Type: Two-way shut-off (Spill Reduction); MALC-HSP Type: Two-way shut-off (Spill Reduction) | Air, Water, Hydraulic oil |
| MULTI CUPLA MAM Type | 7 bar | Rc 1/8 | One-way shut-off (valve on socket side only) | Air |
| MULTI CUPLA MAM-A Type | 10 bar | 1/4 inch to 1/2 inch for MAM-A Type plates with CUPLA; 1/8 inch to 1/2 inch for individual CUPLA of MAM-A-SP Type; 1/4 inch to 1/2 inch for individual CUPLA of MAM-A-ZEL Type | Two-way shut-off | Air, Water |
| MULTI CUPLA MAM-B Type | 10 bar | 1/8 inch (8 and 12 port plates), 1/4 inch (6 and 8 port plates) | Two-way shut-off | Air, Water |
| MULTI CUPLA MAS Type / MAT Type and MALC-01 Type | 70 bar | MAS type 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, 1 inch (R and Rc threads); MAT type M20, M24, M30, M39, M45 thread screw mount; MALC-01 type M14x1 thread screw mount or flange | Two-way shut-off for MAS type and MAT type; One-way shut-off for MALC-01 type | Air, Water, Hydraulic oil |
| MULTI CUPLA MAS Type / MAT Type | 70 bar | 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, 1 inch (MAS type thread); M20, M24, M30, M39, M45 (MAT type thread) | Two-way shut-off | Air, Water, Hydraulic oil |
Pick the MULTI CUPLA MAM-B Type when air or water at 1.0 MPa {10 kgf/cm2} has to be changed over on 6 to 12 ports in one operation and both halves must seal on disconnection, since the two-stage manual lever and the lock mechanism deliver that without any external drive. The MAM Type is one-way shut-off with a valve on the socket side only and is rated 0.7 MPa {7 kgf/cm2}, while the MAM-A Type shares the 1.0 MPa {10 kgf/cm2} rating and two-way shut-off. For higher pressures, look at the MAS Type and MAT Type at 7.0 MPa {71 kgf/cm2} or the MALC-HSP Type at 21.0 to 25.0 MPa {214 to 255 kgf/cm2}.
