Kasco Marine SureSink™ Weighted Tubing is an air delivery line for diffused aeration systems, connecting the air supply to underwater diffusers in pond and lake aeration installations. Its weighted design helps the tubing sink and remain submerged, supporting airline routing along the bottom of the water body. Available in 3/8-inch × 500-foot and 5/8-inch × 500-foot options, SureSink tubing provides two sizes for compatible aeration system configurations. This weighted aeration tubing is suitable for new installations or replacement of existing submerged air supply lines.
