This corrugated polyethylene tubing is designed for bilge pump discharge applications. Its single-layer construction provides resistance against mild chemicals and saltwater, making it suitable for marine environments. The tubing features a clamping cuff every foot, allowing for secure connections. However, it should not be attached to thru-hull fittings below the waterline. With its durable and flexible material, this tubing offers a reliable solution for bilge pump discharge needs.
