Abstract
A twin ferrule tube fitting includes a body configured to be received over a section of tubing, a nut configured to be received by the body over the section of tubing, a front ferrule disposed between the body and the nut, and a rear ferrule disposed between the body and the nut. Tightening the nut into the body causes the front ferrule and the rear ferrule to be driven into the section of tubing, and tightening the nut into the body causes a butt seal to be formed between a protruding surface of an interior of the body and a surface of the tubing.
