Coded workshop couplings, NW 7.2 (standard)

Coded couplings (distinctive quick couplings) of nominal width 7.2 have a coloured sliding sleeve made of aluminium, which facilitates the assignment of the right plug, which is marked with the same colour. The distinctiveness is achieved through a shape coding of the coupling plug and the coupling (octagon, circle, hexagon or triangle). Warning: Standard coupling plugs NW 7.2 as a rule also fit in the coded coupling sockets! The plug profile is compatible with the most broadly used coupling plugs in Germany fitting the Parker-Rectus series 25, 26, 1600 and 1625, TEMA series 1600, CEJN series 320, JWL series 520, 530 and 560), Festo model series KD4/KS4, IMI-Norgren series 238, Aventics series CP1-NW 7 / 7.8.
