Parker offers an alternative to standard polytetrafluoroethylene (PTFE) coatings called ParkerSlick. ParkerSlick
is an external o-ring coating that provides excellent adhesion and friction properties over PTFE. It is dry to the
touch, does not rub off easily and, unlike PTFE, does not leave any visible residue behind. ParkerSlick comes
in an array of colors and offers many significant benefits as listed in the downloadable PDF.
