Quick connect coupling Multi Cupla MAM-B-2S8, brass - Nitto Kohki 349826711
The socket receives the plug of the same size and holds it in the connection. It usually sits on the fixed side of the installation, for instance at the machine or manifold port. Sockets are likewise offered in brass, steel and stainless steel, with an NBR or FKM seal depending on the version. Model MAM-B-2S8, brass, Seal material FKM.

Description
On machines and test rigs, lines are disconnected and reconnected several times a day. The Multi Cupla series from Nitto Kohki covers that job with 120 versions in brass, steel or stainless steel, each available as a socket and as the matching plug.
- Bodies in brass, steel or stainless steel (SUS), so the coupling suits the environment at the installation point.
- Seals in NBR or FKM, which lets the material pairing be matched to the medium being carried.
- Every socket has a plug of the same size, for example MALC-4S and MALC-4P, which keeps spare part stocking simple.
- Sizes 01, 1, 2, 3, 4, 6 and 8 within the same model line, so different port sizes stay inside one coupling system.
- 120 articles in a single series, from the individual coupling to the MAM, MALC, MALS, MALT, MAS and MAT versions.

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 comparison
| 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-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 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 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 |
| 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 |
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}.
