Blue Diamond 1/2 inch weighted air tubing is a self-sinking PVC airline designed for ponds, lakes, and wastewater aeration systems. Its thick-wall construction helps resist kinking, crushing, and airflow restriction over long runs. The tubing remains flexible from -50°F to 140°F and is suitable for fish, plants, and animals. A 1/2 inch inside diameter connects with compatible diffuser stations and supports high-volume airflow from Blue Diamond ET60 through ET250 linear air pumps over long runs.
