Krytox Fluorinated Oils & Greases

Originally developed for the U.S. Space Program, Krytox® Performance Lubricants are a family of fluorinated synthetic oils and PTFE thickened greases that perform where conventional lubricants fail. Krytox® Lubricants exhibit superior lubricity, high load carrying ability and extra wear protection. Excellent for high temperature applications and chemically aggressive environments. Available in general purpose, mil-spec grade and food grades. Some lubricants also have a National Stock Number.


  • High Temperature Stability, up to 800°F / 426°C
  • Wide Operating Range, from -103°F (-75°C) to greater than 800°F (426°C), compared with hydrocarbon lubricants with an operating range of 0°F (-18°C) to 210°F (98°C).
  • Oxygen Compatibility, safe for oxygen service.
  • Chemical Inertness. Insoluble in hydrocarbons, petroleum distillates, water, steam, chemical solvents and acids/bases. Provides extra protection against aggressive chemicals that degrade conventional lubricants.
  • Ionizing Radiation Resistance, more stable than most hydrocarbon and synthetic materials.
  • Compatible with plastics, elastomers, metals and ceramics.
  • Extends Service Life of critical components. Reduces down time and maintenance costs.
  • Low Vapor Pressure
  • Low Outgassing
  • Nonflammable
  • Nontoxic
  • No Migration, contains no silicones.
  • Food Grades (H1 & H2)
  • Aerospace Grades
  • Mil-spec Grades

Facilities Levels NFPA 99, 2005

This is how we interpret these sections. In NFPA 99, 2005

Level 1:  Anesthesia is provided.  If ANY mechanical ventilation is to be expected, the facility clearly falls within this category.

Level 2:  No mechanical ventilation.  A common application would be a nursing home, or a hyperbaric chamber.

Level 3:  Medical gas is not required to sustain life, such as the gasses in a dental office.

Cut and Cap Certification Requirements

Opinon based on NFPA 99, 2005

NFPA 99, 2005  states that all pipeline down stream of a break in the pipeline must be verified. What if the break is a cut and cap?  NFPA also states that any time the system is remodeled or repaired it should be verified to confirm that it meet the NFPA standards.
