The plug is the insert half of the connection and enters the socket of the same size. It is normally fitted to the side that moves, gets swapped or travels with the job, such as a hose, a tool or a test piece. Plugs in this series are available in brass, steel and stainless steel with NBR or FKM seals. Model MAM-1TP-16, brass.
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.

MULTI CUPLA MAM Type suits manual plate changes on air lines at 0.7 MPa {7 kgf/cm2}, where a valve on the socket side alone is sufficient. Where the ports must stay closed on both sides, MAM-A Type and MAM-B Type are rated 1.0 MPa {10 kgf/cm2} with two-way shut-off, and MAS Type and MAT Type reach 7.0 MPa {71 kgf/cm2}. MALC Type covers 1.0 MPa {10 kgf/cm2} up to 25.0 MPa {255 kgf/cm2} depending on the version.
