Qruck not only supply normal storz coupling from 1’’- 6’’, but also supply large storz coupling from 8’’- 20’’. Regarding large storz coupling, we choose high strength forging Aluminum or stainless steel for the coupling shank; and we also offer heavy segmented bindings for safety holding. According to different usage requirements, we produce and offer lockable storz coupling, flange storz coupling, and mulit-lug storz coupling. And they are used widely in the connection with hose, pump, valve, water divider, water collector, and other equipments.
Qruck's large Storz Coupling is the sexless, quarter-turn coupling designed and produced for nominal sizes DN200 and above, featuring a reinforced body, oversized gasket, and larger handles to safely handle the high flow rates (up to 12,000+ L/min) and mechanical loads of large-diameter firefighting or industrial water supply hoses. And our Large Storz couplings (8" and up) are for massive water supply lines used in wildland fires, industrial complexes, or as fixed fire mains, where a single coupling may weigh over 10 kg and requires two people to connect.
