Laguna PVC tubing provides an excellent combination of strength and flexibility required in a variety of pond applications. The tubing is made of tough industrial strength PVC which provides reliable performance under the most extreme conditions. It is particularly well suited for situations where sharp turns are required and eliminates the need for elbow connectors. Flow rates are never compromised even in the sharpest bends. The non-toxic tubing is safe for pond use and will not harm fish or plants. Size: 9mm (3/8") in diameter 25 ft
