Our Black Flexible PVC Pipe, is commonly used for water gardening (ponds, waterfalls, fountains, etc.) drains, fish hatcheries, irrigation, farming and gardening, and other applications where the utilization of rigid pipe is either not practical or not desirable. Commonly referred to as pond hose, flex tubing and flexible PVC, our black flexible PVC hose is strong and long lasting, as well as extremely flexible. The black color prevents sunlight penetration which makes it practically invisible underwater. The advantage to using black flexible PVC over rigid pipe is that it can be easily routed in any direction without the use of multiple fittings, which makes plumbing your pond, fountain or waterfall much simpler. It can be used in areas where space (for fittings) is limited and/or in situations that rigid pipe is difficult or impossible to work with. It is sunlight and ozone resistant.
