This Flexible PVC Pipe, commonly referred to as "flex tubing", "spa tubing" and "flexible PVC" is perfect for use with pools, spas, hot tubs, water gardening (ponds, waterfalls, fountains), aquariums and fish hatcheries, irrigation, farming and gardening, sprinkler lines and other applications where the utilization of rigid pipe is either not practical or not desirable. Strong and long-lasting, this hose is ultra-flexible, and 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. It is sunlight, ozone and mildew resistant (although we do not recommend installations in continual sunlight). Our Flexible PVC Pipe easily conforms to almost any contour, and experiences less heat loss than comparable copper or steel pipe. A rigid internal PVC spiral resists crushing and impact issues, and this PVC pipe can be used for above-ground or under-ground installations (with proper cushioning). It can also be used as a conduit to run protected electrical, cable, phone or fiber optic lines and can also be used as a protective liner for softer hoses or tubes. Trimming or cutting is much simpler than with rigid PVC pipe (it can be cut with PVC pipe cutters, a standard hack saw, a carpenters saw, etc.) and it accepts standard Schedule 40 fittings. It can be easily glued using any good commercially available glue for flexible or rigid PVC. It eliminates back-pressure caused by sharp turns created by multiple fittings, which increases the efficiency of your system and lowers your overall operating/energy cost. Each fitting eliminated with this highly-flexible pipe is one less fitting that can fail and cause your system to leak. It also coils easily for storage and transport.
