A.T. Airline

Aquatop’s Premium Airline is available in a variety of fun and vibrant colors that are ideal for any aquarium use. Made from flexible plasticized PVC, the airline is kink resistant and remains flexible after long periods of use. The 1/8-inch inside diameter (ID) makes it great for use with air pumps, dosing systems, CO₂ reactors, CO₂ injectors and more (each sold separately). You’ll love the way your tank pops with this airline! A check valve (sold separately) is recommended for all setups.
