Product Name: Aquarium Air Valve Key benefits - Precisely control oxygen flow: Adjust or shut off air to match the needs of fish, plants, or aeration devices without moving the pump. - Split one supply into two outputs: Feed two air lines from a single inlet for air stones, sponge filters, or diffusers. - Durable, corrosion-resistant construction: Copper, nickel-plated body resists corrosion in wet environments for reliable service. - Simple, manual operation: Lever allows quick, tactile control — no tools or electricity required. Features and specifications - Material: Copper, nickel plated for corrosion resistance and durability. - Inlet connector diameter: 3/8 inch (connects to your air pump or aerator outlet). - Outputs: Two outlet ports, each 3/16 inch diameter (connects to standard 3/16 inch aquarium tubing). - Function: Manual air flow control and on/off shutoff for each outlet; splits one inlet into two controlled outputs. - Applications: Designed for aquariums, ponds, and other aquaculture uses where controlled aeration is required. What this product solves - Prevents over-aeration and stress: Fine-tune oxygen delivery to avoid excessive bubbling or noise. - Eliminates the need for multiple pumps: Use one pump to serve two devices and balance flow between them. - Easy maintenance and control: Quickly isolate a line for cleaning or equipment changes without stopping the entire system. Compatibility and installation - Connect the 3/8 inch inlet to the outlet of your pond aerator or aquarium air pump. - Attach standard 3/16 inch tubing to each of the two outlet ports. - Use the lever to adjust flow or fully close an outlet when needed. - No special fittings required if your tubing matches the specified diameters. Performance and care - Manual lever provides responsive control over air volume to each outlet. - Copper with nickel plating reduces corrosion risk in damp environments; wipe clean periodically and inspect for wear. - Suitable for freshwater and many pond applications; avoid exposure to aggressive chemicals not intended for aquaculture equipment. Use scenarios 1) Small aquarium with a single air pump: Split one pump outlet to run two air stones in separate tanks or zones, then balance flow to each stone with the valve lever. 2) Breeding or quarantine setup: Reduce or shut off air to a specific tank quickly during handling or treatment while maintaining aeration elsewhere. 3) Garden pond or shallow aeration: Connect to a pond aerator to control airflow to multiple diffusers, enabling targeted aeration around plants or shallow areas. Package notes - Includes one Aquarium Air Valve, copper nickel plated, with 3/8 inch inlet and two 3/16 inch outlet ports. - Intended for manual control and tubing connection in aquarium, pond, and aquaculture systems. Purchase this Aquarium Air Valve when you need a compact, durable, and easy-to-use solution for splitting and controlling air flow from your pond aerator or aquarium air pump.
