PVC Flex Tubes

Best for: Enclosed sink, tub, and shower faucets; toilets where tubing is shaded from direct sunlight.

Strong and durable, PVC flex tubes are made of a PVC (polyvinyl chloride) outer core that is usually braided with nylon, and an inner core made of solid PVC. This type of flex tube is often the least expensive option. But although they are cheap, they are very flexible, offering amazing strength and ease of use.

Keep in mind that PVC flex lines are not as corrosion-resistant when used in an exposed area—sunlight can weaken the material. They are suitable for hot and cold water and are a great, inexpensive option for faucet and toilet connections alike. These inexpensive PVC flex lines are not quite as durable and long-lasting as braided nylon or other types.
