Connect your SBS refrigerator, water filter, or osmosis system to the cold water line, e.g., under the sink, using the shut-off valve for 1/4-inch plastic hoses. Takes up little space! This adapter requires no sealing (Teflon, hemp yarn), a Y-adapter, or a splitter. The shut-off valve allows you to stop the water flow by using the tap, for example, to change filters. Thanks to the 3/8-inch adapter, the filter requires no separate connection. You can simply screw it between the cold water line and the tap's hose (reinforced hose) and thus supply your appliance with water while using your tap as usual.
