This durable 6mm High-Pressure CO2 Tubing is specially designed for use with pressurized CO2 systems in planted aquariums. Unlike standard silicone air line, this pipe features a thick, robust wall that prevents the CO2 gas from escaping (leaking) or diffusing through the tubing material, ensuring maximum efficiency and safety. It is sold per foot at 40 Tk per foot. To order, adjust the quantity to the total number of feet you require (e.g., quantity 5 = 5 feet of pipe). Essential for connecting your regulator to your bubble counter and check valve.
