## Long description

Flexible aquarium silicone tubing C2G with an inner diameter of 4 mm, outer diameter of 6 mm and a length of 3 m. The tubing is intended for air and low-pressure water lines in aquariums, external filters, pumps and CO2 systems. Made from chemically inert silicone material, the hose resists biofouling and maintains flexibility across a wide temperature range, making it suitable for standard home and hobby aquarium installations.
Advantages
This silicone tubing offers a smooth inner surface that reduces buildup and facilitates steady flow for air pumps, CO2 delivery and low-pressure water transfer. Its elasticity and kink resistance allow easy routing around tanks and equipment while preserving a reliable seal on standard 4 mm fittings. The neutral, chemically inert composition prevents reactions with aquarium additives and CO2, and the tubing retains flexibility without becoming brittle during regular aquarium use.
Suitable for
Air pump connections and airline routing in freshwater and saltwater tanks
Low-pressure water lines for external canister filters and small pumps
CO2 delivery lines for planted aquariums and reactors
Bubble counters, check valves and drip systems in aquarium setups
Key specifications
Inner diameter: 4 mm
Outer diameter: 6 mm
Length: 3 m
Material: chemically inert silicone
Designed for low-pressure air and water applications
Flexible and resistant to biofouling
How to use
Cut the tubing to the required length with a sharp scissors or tubing cutter to ensure a clean end. Push the tubing firmly onto compatible 4 mm airline fittings, barbed connectors or CO2 system outlets until seated to form a secure connection. Route the hose avoiding tight bends that could create flow restriction; use clips or tubing holders to secure runs along the aquarium rim or cabinet. Replace any section showing persistent cloudiness, cracks or loss of elasticity.
Usage recommendations
For best performance, flush new tubing with clean water before first use to remove manufacturing residues. Inspect connections periodically and replace tubing every 1–2 years or earlier if signs of wear appear. Avoid exposure to strong solvents or hydrocarbons that can degrade silicone. When used for CO2 systems, ensure secure fittings and check for leaks with soapy water or a leak detector designed for gas systems.
