LINLAN Easy Water Refill CO2 Bubble Counter with Check Valve and Water Adder for Planted Aquarium CO2 Regulator (Air Pipe Connection) - size: Air Pipe Connection

About this item

• 【Easy Water Refill Function】Are you always annoyed by the lack of water in the bubble counter, but it is always very difficult to remove the bubble counter? With the LINLAN water-fillable bubble counter, you can directly add water from the small hole without disassembly, simplifying the operation.
• 【Includes Water Injector】With the water injector, you don't need to turn off the CO2 when adding water. Simply align the injector with the small hole on the bubble counter, ensure a tight connection with a little force, and push the water into the counter to refill it.
• 【Check Valve】The bubble counter has a built-in check valve. In some cases, there may be a pressure difference in the air pipe, and the check valve can prevent water from flowing back, thereby protecting the equipment.
• 【Starting Pressure】CO₂ - 3 bar; O₂ - 1.5 bar. If using a reaction system to generate carbon dioxide, ensure the pressure is sufficient to drive the bubble counter.
• 【Compatible Size】The bubble counter is compatible with 4/6 mm (3/16 inch inner diameter) CO2 tubes. The thread connection type fits M10x1 male thread connectors.
