Flexible PVC hose that can be used for pond or hot tub installations. Available in sizes ranging from 1" to 2" diameter. This hose uses white PVC fittings (glued fittings). Thicker wall is suitable for underground burial and is very resistant to crushing and punctures. Not as flexible as reinforced pond hose. PVC hose and PVC fittings have the advantage that the fittings are on the outside of the hose and do not restrict water flow.
