Got a powerful air pump but need to control the flow to multiple tanks or devices? This ZZHXSM 2-Way Air Flow Control Valve is exactly what you need. Made from polished stainless steel, it's corrosion-resistant, durable, and looks sleek in any setup. Each outlet has its own lever, so you can adjust the airflow to two different lines independently — perfect for balancing aeration in multiple tanks or fine-tuning bubble walls and ornaments.

It's super easy to install: just connect your main air pump line to the inlet (4mm / 0.16 inches), attach your airline tubing to the outlets, and you're set. The levers give you precise control, from fully open to completely closed, so you can dial in the perfect flow for each application.

Ideal for freshwater and saltwater aquariums, fish tanks, shrimp tanks, pond aerators, hydroponics, and more. Comes as a 2-pack, so you can split one pump across four lines if needed. A must-have accessory for serious aquarists or anyone who wants better control over their aquarium's air supply. Keep your fish happy and your tanks well-oxygenated with this simple, effective valve.
