Quick-connect couplings consist of two components – coupling socket and plug. They are the ideal interface to connect or disconnect the flow of gaseous or liquid media in lines safely and quickly. This enables a rational and reliable connection and changes of systems, aggregates, devices and their applications. Series and shape of a quick-connect coupling are dependent on the medium conveyed in the hose and the prevailing pressure conditions. Quick-connect couplings are used for the conveyance of air, water, oil, acids or various gases. Here you will find single-sided and double-sided blocking quick connect couplings up to I.D. 19, asymmetrical couplings in different sizes and hydraulic couplings standardised to ISO. Our safety couplings are available in swivel, rotating and push button design and in combination with sliding valve and quick connect coupling. RIEGLER couplings are available with a flow of up to 8700 l/min and in EURO, ARO210 and ISO 6150 C plug profiles. The range of materials goes from bright and nickel-plated brass to different variants of stainless steel up to aluminium, plastic, steel and zinc die casting.
