Abstract

A threaded component for connecting piping employed on motor vehicles includes a thread formed thereon and at least one unthreaded, contacting surface. A first coating having a first coefficient of friction is disposed on at least a portion of the thread, and a second coating having a second coefficient of friction is disposed on at least a portion of the unthreaded, contacting surface(s) of the threaded component. The first coefficient of friction is greater than the second coefficient of friction. In an embodiment an anti-corrosion coating is provided between the coatings and the component.
