Super flexible and almost impossible to kink
(For standard irrigation systems, for Blumat systems refer to 8mm Superflex)
This tubing is more expensive than typical 1/4", but is extremely easy to use. We like to put it after a valve at the end of a loop or line and use it as a handy water source. Being so flexible, it's easy to fill a little container, give a plant a little extra water, etc.

It's extruded from a specially formulated silicone with a hardness rating of 60 Shore A and heat stabilized to ensure re-use and can handle temperatures up to 500°F (260C). It's non-staining, reuseable, and we can cut this to the length you need.

We also have this in 100' rolls.
