About the product
4-Outlet Control Valve: Manually and individually control the air flow of each outlet port for your multiple needs. Great for running 4 filters or air stones at the same time.
For Standard Hoses: Both the inlet and outlet ports are perfectly compatible with 3/16" ID airline tubing. Made of reliable chromium copper which allows for smooth air flow without air leakage or restriction. Strong Suction Cups: The soft and flexible clear suckers are easy to adhere to any smooth surface without falling. Theyll turn milky white after being used in water for a period of time. Sturdy Hose Clips: Diameter: 0.2". Suitable for holding standard 3/16" ID or 1/4" OD hoses or CO2 hoses. Theyre freely rotatable to easily adjust the positions of tubing. Non-return Valve: The one-way check valve can effectively protect your air pump by preventing aquarium water from back siphoning during a power outage or pump pause.
