Quick-release couplings, ARO/ORION NW 5.5

These quick-release couplings and coupling plugs with ARO profile or ORION profile nominal width 5.5 are mainly used in Switzerland, Belgium, the Netherlands and Luxembourg. The couplings are compatible with ARO couplings series 210, ORION couplings series 44510, CEJN quick-release couplings series 300, Rectus couplings series 14 and 22 and JWL coupling series 512, 522, 523 and 572. Attention: Despite the similar appearance of the coupling sockets ( ARO/ORION) with the coupling sockets with a nominal width of 7.2 that are widespread in Germany, these couplings are not compatible!
