We needed the tubing to finish up our home water purifier. This tubing is very solid and avoids kinks. The sidewalls are thick so that high pressure water is not an issue. It is easy to cut and easy to work with while we finished the home water purification setup. There is no odor or taste from the tubing. We also had the water tested, post installation, and there are not any chemicals or other contaminants present. Super happy!
I didn't order this with any immediate use in mind but I'm always in the middle of one project or another and I felt this tubing would be very useful to have on hand.
