Lubrication

All Alkon valves are pre-lubricated with PTFE-based grease and will operate dry (with no additional
lubrication). However, a lubricated system will greatly extend the service life of any valve. The following
oils are popular, easily obtained fluids that are recommended for use with Alkon valves: Gulf Harmony
47, Moble DTE Medium, Shell Tellus 29, Texaco Rondo B., Schivis 47 and Sunnis 921. Many other fluids are
acceptable lubricants providing they do not contain detergents that will attack Buna N or Viton seals.
