A 3-way metal air valve splitter divides a single incoming air source into three separate channels, allowing independent control over the airflow of each branch. These heavy-duty components are widely used to manage multiple pneumatic lines, aerate multiple aquarium tanks from a single pump, or balance oxygen distribution in aquaculture and hydroponic systems.

These are small, stainless steel lever-style gang valves designed for fish tanks, shrimp breeding racks, and hydroponic setups.

• How they work: A single air pump pumps oxygen into the main inlet, and four individual small lever switches allow you to adjust or completely shut off the bubbles going to individual sponge filters or air stones.
• Compatibility: They typically fit standard 4mm/6mm silicone airline tubing.
• Note: Intended for low-pressure air pumps and are not compatible with high-pressure CO₂ systems.
