Finest-Filters 2-in-1 Metal Bubble Counter & Check Valve

Product Description

This 2-in-1 metal bubble counter with built-in check valve offers a clean and compact solution for monitoring gas flow while protecting your system from backflow. It’s available in two connection types to suit different setups: Air Line is designed for standard 4/6 mm air line tubing, ideal for use with air pumps or low-pressure CO₂ setups. CO₂ connects directly to CO₂ regulators, needle valves, or splitters — perfect for pressurised planted tank systems. The integrated stainless steel check valve adds an essential layer of protection, helping prevent water from entering your regulator or pump. With its durable metal housing and transparent chamber for bubble counting, this tool is a practical upgrade for any aquarium gas system.
