Connect your refrigerator, water filter, or reverse osmosis system to the cold water line—for example, under the sink—via the shut-off valve for 1/4 inch plastic pipes. Compact design saves space. This adapter requires no sealant (such as Teflon tape or hemp), and no Y-adapter or distributor is needed. The built-in shut-off valve stops water flow when activated—ideal for filter changes. With the included 3/8 inch adapter, no separate water connection is required for your filter. Simply install it between the cold water pipe and the faucet hose (braided stainless steel hose) to supply water to your appliance while maintaining normal faucet use. Includes: 1x adapter with integrated gasket (3/8" female thread x 3/8" male thread x 1/4" JAKO hose connection). Water connection adapter with gasket (3/8" female thread x 3/8" male thread x 1/4" JAKO pipe connection). No sealant required. No Y-adapter or multi-way manifold required. Space-saving design. Material: chrome-plated brass. Designed for connecting 1/4 inch (6.35 mm) plastic pipes to cold water lines—for refrigerators, water filters, and reverse osmosis units—typically installed under the sink. Features a one-piece T-connector and rubber sealing ring to prevent leaks. The 1/4" compression fitting securely holds the plastic hose, even under high pressure. Precision engineering ensures reliability, ease of use, and simple installation. The shut-off valve allows quick water flow control—e.g., during filter replacement. The 3/8 inch adapter eliminates the need for an additional water connection, enabling direct integration between the cold water supply and faucet hose.
