  • Copper Tubing Color Coding

    Under the UPC that we follow in California, ridgid copper tubing is required to be color coded by type. Red for Type M, Blue for Tyle L, etc.

    I was required to learn this as an apprentice, and if I recall, the were a few questions on the California contractor's exam ot the issue.

    The last few years I have noticed that there is no color coding at all on the copper I recieve.

    I don't like that, because there are many times where we are using several grades of copper on a job depending on the use and the spects.

    Has anyone noticed this? Your thoughts please.

      Not only is it printed on the side in color, the information is also lightly engraved.
