Abstract
A tubing and ferrule assembly for use in joining a clad tubing to a fitting. The ferrule is bound to the clad tubing, which includes a partial jacket of stainless steel, such that the inert core protrudes from, and has a common outer diameter with, the jacket. The ferrule is bound to the jacket slightly more distant than necessary for the inert core to contact a fitting. When the ferrule is retained in place, the inert core is compressed and provides a true zero dead volume connection between the clad tubing and the fitting.
