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.
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.
Dimensions in millimetres. Values in brackets apply in the connected condition.

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}.
