Most Grohe kitchen pull-out faucets use a part called the Quick Connection Coupler to connect the pull-out hose to the cartridge’s mixed-water outlet. Over the years, Grohe has developed several versions. Some versions are improvements over older models and some are made for specific types of faucets (CalGreen-compliant faucets, for example). And there’s more to Quick Couplers than a hose connection; they also contain a check valve and some (but not all) include flow restrictors.
