Highly flexible vinyl plastic tubing serves many purposes for your small water volume plumbing needs. Use it for an ice maker or a small plant watering system. Its smooth surfaces never corrode, and prevent the build-up of any bacterial growth, either inside or outside of the tubing. To install a fitting on the end of the tubing, you need a compression ring commonly called a ferrule. Use a plastic ferrule and never brass, which could dig into the tubing and cause a leak.
