Our Non-Kink Flexible PVC tubing commonly referred to as non-kink, kink free tubing water garden hose, pond tubing, flex pond and corrugated tubing is perfect for use with water gardening ponds, waterfalls, fountains, aquariums and fish hatcheries, drains, light farming and gardening and light irrigation. While it is not as strong and durable as our flexible PVC pipe, it is somewhat more flexible and lighter. Corrugated on the outside for strength and smooth on the inside to speed water flow, reduce material build-up and reduce friction, this lightweight tubing can easily be routed in any direction necessary without the use of multiple fittings, thus simplifying plumbing layouts and the installation of your job. It can be used in areas where space (for fittings) is limited and/or in situations that simply will not accommodate rigid pipe.
