Coded workshop couplings, NW 7.2 (standard)

Coded couplings (unmistakable quick couplings) with a nominal diameter of 7.2 have a colored sliding sleeve made of aluminum, which enables the matching plug, which is marked with the same color, to be assigned. The uniqueness is achieved by shape coding of the coupling plug and the coupling (octagon, circle, hexagon or triangle). Attention: Standard coupling plugs NW 7.2 usually also fit into the coded coupling sockets! The plug profile is compatible with the coupling plugs most widely used in Germany, suitable for Parker-Rectus series 25, 26, 1600 and 1625, TEMA series 1600, CEJN series 320, JWL series 520, 530 and 560), Festo series KD4/KS4, IMI -Norgren Series 238, Aventics Series CP1-NW 7/7.8.
