Packaging and contents 1 x 2way aquarium air pump connector/valve 2 x non (check) valves 8 x suction cups Key benefits and how it solves problems Split and control a single air source: convert one pump inlet into two independent outputs to run two air stones, filters, or decorations from a single pump. Precise, manual flow control: the lever valve lets you adjust or shut off airflow to either output without changing pump settings. Prevents backflow and crosscontamination: included check valves stop water or air from traveling back into the pump or into the other line. Secure, durable construction: made of chromium copper material and designed so air will never leak out, reducing maintenance and improving reliability. Specifications and compatibility Inlet connector diameter: 3/8 inch Output diameter (each): 3/16 inch Material: Chromium copper Includes suction cups for secure mounting on aquarium glass Compatible with standard 3/8 inch inlet tubing and 3/16 inch airline tubing used with most hobby air pumps and accessories Performance and usage notes Manual lever provides smooth, immediate control of oxygen delivery or on/off switching for each outlet Compact, lightweight design for easy installation and placement inside or outside the tank Non valves are preincluded so you can protect the pump and maintain independent outputs right away Practical use scenarios Shared pump setup: run one pump to two small tanks or divide airflow between an air stone and a sponge filter in a single tank. Maintenance and isolation: temporarily shut off one output when cleaning or replacing accessories without interrupting the other line. Targeted aeration: reduce airflow to a planted area while keeping higher flow to a biological filter, optimizing conditions for both plants and beneficial bacteria. What you get A readytoinstall 2way valve splitter with check valves and suction cups for reliable, adjustable airflow management across aquarium applications.
