Our standard Flexible Black PVC pipe is great for use in situations where there are lots of turns and curves, or where working space is tight. Our ultra flexible black PVC is even better. One of the strongest and most flexible products on the market, Ultra Flex PVC is perfect for use in pond, water garden and fountain applications. Designed with a tighter, rigid spiral within a more flexible wall, we are able to provide a pipe that is an installers dream. This is not a “thin wall” pipe. Stronger and even more flexible, this thicker wall design is now the only choice for professional contractors and homeowners alike. With all the great attributes of our standard black flexible PVC pipe, the increased flexibility of our Ultra Flex will save installation time and headaches. Quite simply, you will not find a more flexible PVC pipe in the market anywhere.
