Mould couplings are developed especially for use with liquid media with temperatures up to +160°C (e.g. on plastic processing machines). The DN 6 couplings (tap diameter 9 mm) are compatible with Hasco couplings of series Z8.../9... and available in brass or stainless steel. Coupling sockets and plugs are available with and without valve (i.e. shut-off or non-shut-off). To couple a coupling plug with value, the coupling socket must also be equipped with a valve. The hose fittings are designed for hose fastening using hose clips or suitable for push-lock push-in hoses.
