Vertex Bottomline Self-weighted Tubing 0.625" – 500' Spool

The Vertex Bottomline Self-weighted Tubing 0.625" 500' Single Spool is engineered for reliable, long-term performance in pond and lake aeration systems. Built to sink naturally and stay in place without the need for additional weights, this self-weighted tubing streamlines installation and ensures consistent airflow delivery to diffusers.

Made from durable, kink-resistant materials, this 5/8" inner diameter tubing is optimized for maximum air flow with minimal friction loss. Its black exterior resists UV degradation, algae buildup, and harsh environmental conditions, making it ideal for submersible use in aeration systems for ponds, lakes, and other aquatic environments.

Each 500-foot spool provides generous length for multiple diffuser placements or larger water bodies, reducing the need for couplings and maintaining efficient operation. Its rugged yet flexible design allows it to conform to uneven underwater surfaces while maintaining a consistent depth.

Whether you’re servicing a small pond or a large lake, this self-weighted tubing delivers quiet, efficient, and worry-free operation throughout the year.
