@Alan,
Yes, but this is 1/16" OD tubing. It came from McMaster Carr. I just sent them a picture and asked them to send me new tubing and 2 new ferrule sets for my compression fittings. I am sure they will respond quickly. In the mean time I have just put some JB Weld over the holes. Hopefully that will work and tomorrow I an re-start the experiment. That is, heaven forbid, I don't find yet another leak!
I can't tell from the text here, but be careful with compression fittings. Swagelok is NOT compatible with generic fittings. It may work for awhile, but not as reliable as staying within one manufacturer. You have to call them, but the folks at McMaster are good at identifying the manufacturer for individual things that they sell.
