CO2 Tubing Connector Set

The CO2 Tubing Connector Set provides all the push-fit fittings needed to route, split, and redirect CO2 lines throughout an aquarium setup without tools or adhesives. The set includes straight couplers for joining tubing lengths, 90-degree elbow connectors for tidy corner routing, T-pieces for splitting a single CO2 line to two diffusers, and end-caps for temporarily sealing unused lines. All connectors are sized for the standard 4/6mm CO2 tubing used universally in aquarium CO2 systems. The fittings are manufactured from CO2-resistant materials that will not degrade or crack with prolonged gas exposure. Ideal for hobbyists running multiple tanks from one regulator, or anyone setting up a new CO2 system who wants a professional, leak-free plumbing result.
