Kasco SureSink Feeder Tubing

Product Details

Kasco SureSink Feeder Tubing is designed to deliver air from a shore-mounted compressor to submerged diffuser locations while naturally sinking and staying on the pond or lake bottom. Its self-weighted construction helps create a cleaner, more professional installation by reducing the need for added weights and helping the airline stay where it is intended throughout the run. Kasco positions SureSink as a durable, flexible weighted airline option for aeration systems, with 3/8” and 5/8” sizes available depending on the application. It is a strong choice for new aeration installations, system expansions, and replacement tubing where dependable underwater routing and a clean finished appearance are important. For longer runs, Kasco-related product guidance commonly recommends 5/8” tubing for distances over 300 feet.
