Not for leak testing! It has a valve at the bottom so when used with a compression tester it only measures what is coming out of the cylinder. When used as an extension to a leak test, you get such wonderful results (100%) that you find out what's wrong pretty quickly. The valve prevents air from escaping the extension into the cylinder and then out. :-/ I'm more confused about these 20 seconds, in which I realized that something can NOT be right.
