Key Facts

  • Split your CO2 supply from one source to two outputs.
  • Easy to install, requiring no modification to the regulator.
  • No need to purchase multiple regulators and cylinders.
  • Accurately adjust flow rate for each output using accurate needle valve.
  • Very durable and will never rust.
  • For 4/6mm tubing.
  • Extension to ensure clearance of regulator body and pressure gauges.
 

Description

Transform a single CO2 regulator into a dual-output system with this high-quality splitter, allowing you to run multiple diffusers or supply CO2 to multiple aquariums, all from one cylinder. It’s a cost-effective alternative to buying and maintaining additional regulators and gas cylinders.

Each output features its own precision needle valve, enabling independent flow control for optimal CO2 distribution across all connected outputs.

Installation is quick and simple: the splitter screws directly onto your existing regulator’s needle valve, and an included extension ensures clearance from the regulator body and pressure gauges.

    Great way to add CO2 for two tanks without needing a second regulator or cylinder. The needle valves are precise and make adjusting the CO2 levels very easy.

    It's super easy to set up and saves you the hassle (and cost) of buying another regulator and cilinder. It's super easy to set up and saves you the hassle (and cost) of buying another regulator and cilinder.

    Easy to use and much cheaper than needing to buy another regulator and cylinder. Each output is separately controlled which is great. Easy to use and much cheaper than needing to buy another regulator and cylinder. Each output is separately controlled which is great.
