Yes, type L. It is thicker/softer than type M. Both will probably work fine.`

I agree with the rest of the guys about hard piping the lines. I have always went with galvanized pipe though, I might have to try the copper piping in the future. I would definitley get a filter system for taking any water, oil and moisture out of the line especially if you plan on ever painting. I have used the Sharpe Model 6760 unit, it is a three stage unit that uses Desiccant beads in the last stage to remove all the moisture. Here is a link to the product that I am talking about.

The automotive store that we get all of our paint products from highly recommends this one. It is a little pricey but it is well worth it. I just looked on ebay and there was a new one for $400. I have had mine for about 8 years and have replaced the desiccant beads a few times and the filter for the oil seperator once. Other than a few maintenance issues, the unit has performed flawlessly. If you like to save money like I do, you can bake the desiccant beads on an old cookie sheet (with sides) in the oven and dry them out.
