Apiezon L Grease

Apiezon L Grease is a silicone- and halogen-free ultra high vacuum grease suitable for use scientific and industrial applications. L Grease has the best vapour pressure properties of all the Apiezon products and is therefore suitable for use in ultra high vacuum applications. L Grease is regularly used by highly respected organisations such as The European Space Agency, NASA and NATO.

Apiezon L Grease is designed for use at ambient temperatures (generally between 10 to 30°C / 50 to 86°F). If you are looking for a grease capable of performing at higher temperatures, Apiezon AP101 or Apiezon H Grease may be more appropriate.
