Weighted Airline for Pond Aerators | Self-Sinking Airline Tubing

Create a clean, professional pond aeration installation with the Outdoor Water Solutions Weighted Airline. Designed to remain submerged without the need for additional anchors or weights, this self-sinking airline tubing keeps your pond aeration system organized while delivering reliable airflow from the compressor to the diffusers.

Unlike standard airline tubing that floats and can become tangled or exposed, the OWS Weighted Airline naturally rests on the pond bottom, helping maintain an efficient and unobtrusive aeration system. Its heavy-duty construction also protects the airline from movement caused by wind, waves, and changing water conditions.

Manufactured from thick-walled, UV-resistant material, this premium airline is built to withstand years of continuous underwater use. The flexible, kink-resistant design allows for easier installation while maintaining consistent airflow to maximize diffuser performance and oxygen transfer.

Compatible with all Outdoor Water Solutions pond aeration systems and most standard aeration fittings, the OWS Weighted Airline is an excellent choice for residential ponds, farm ponds, fishing ponds, and commercial water features. Whether you're installing a new aeration system or extending an existing one, it provides the durability and reliability needed for long-term pond health.
