Workshop safety couplings, NW 7.2 (standard)

Couplings with a nominal width of 7.2 mm are by far the most common coupling types in Germany. The couplings are compatible with Parker-Rectus series 25, 26, 1600 and 1625, TEMA series 1600, CEJN series 320, JWL series 520, 530 and 560), Legris series 25 and 26), Parker series PE and PEF, Prevost series E ... 07, Festo series KD4/KS4, IMI-Norgren series 238, Aventics series CP1-NW 7 / 7.8 and many other manufacturers. The safety couplings according to ISO 4414 / EN983 differ from the standard couplings in that the coupling plug is first vented when uncoupling before it is completely uncoupled. In this way, the whiplash effect that may occur with a standard clutch can be reliably prevented.
