Pond Aerator Airline Tubing | Weighted | 3/8", 1/2", and 5/8" ID

The OWS Weighted Airline is designed for pond owners who want a hassle-free, professional setup. Unlike standard tubing that floats and requires external anchors, this self-sinking airline stays submerged on the pond bottom, keeping your aeration system tidy and efficient.

Built from thick-walled, UV-resistant material, it delivers years of reliable underwater performance without cracking, stiffening, or splitting. Its flexible, kink-resistant design makes installation simple while ensuring uninterrupted airflow to your diffusers.
Perfect for smaller ponds or targeted aeration zones and is compatible with all Outdoor Water Solutions aeration systems and standard fittings. It’s the convenient, durable choice for dependable pond aeration.
