Airline Tubing Clear 3m

This clear airline tubing is the universal connector for all air pump-based aquarium equipment. At 4mm internal and 6mm external diameter it fits the standard barbed fittings found on air pumps, airstones, diffusers, gang valves, and check valves without adapters. The flexible material resists kinking and remains pliable even in cold conditions, making routing behind tanks and through cabinets straightforward. The 3m length suits most single-tank setups with room to spare. Cut to length as needed; offcuts can be used for multiple shorter runs. UV-stable and aquarium-safe, this tubing will not discolour water.
