This 4-way CO₂ splitter lets you supply multiple aquariums from a single regulator. Each outlet is equipped with its own precision needle valve for fine adjustment. Built from stainless steel, it is durable, corrosion-resistant, and designed for long-term use in pressurized CO₂ systems.
Outlets: 4, each with a dedicated needle valve
Material: Stainless steel body and fittings
Riser Height: 36.5 mm (~1.44″), provides clearance for regulator gauges
Threading: Standard M10×1 CO₂ regulator thread
Tubing: Fits standard 4/6 mm CO₂ tubing
Attaches directly to CO₂ regulators with M10×1 threading.
Each outlet connects to CO₂ tubing, which can then run to accessories such as bubble counters, check valves, and diffusers.
For long tubing runs, add a check valve closer to the diffuser to prevent water backflow.
Works with our inline bubble counter if you want the splitter positioned away from the regulator.
Supports four aquariums directly, and can be linked to additional splitters for larger setups.
Q: How many tanks can I run with this splitter?
A: Up to four directly, or more if chained with additional splitters.
Q: What do the outlets connect to?
A: Each outlet connects to CO₂ tubing. From there you can add accessories like bubble counters, check valves, and diffusers in sequence.
Q: What thread does it use?
A: Standard M10×1 regulator thread, compatible with most aquarium CO₂ regulators.
Q: Can it be used away from the regulator?
A: Yes. Pair it with our inline bubble counter to position it remotely for flexible CO₂ distribution.
