Soft Plastic Tubing for Air and Water

This general purpose PVC tubing is the industry standard for air and water applications. Tubing is clear, so you can easily monitor flow. It is flexible to easily bend around objects.
Masterkleer tubing is more economical than Tygon tubing.

Build a compressed air system in half the time it would take to build a copper or steel system. Also known as Unipipe, this pipe is part of a quick-connect system. The compatible fittings connect to this pipe when you finger tighten their collar and then use a wrench for the final quarter turn. A compression ring and O-ring inside the fitting seal it onto this pipe.
Choose blue or gray pipe for easy identification. Blue pipe is often used for compressed air systems. Gray pipe is often used for vacuum systems.
Use a deburring scraper (sold separately) to smooth rough edges left behind after trimming the pipe to size.

Place the tool over the end of your tube and twist to deburr.
