Understanding Hydrogen-Safe Lubricants

Hydrogen-safe lubricants are specially designed to withstand the unique challenges of hydrogen-rich environments. Industries that rely on clean hydrogen—whether for fuel or manufacturing—depend on these lubricants to maintain safe and efficient operations.
Hydrogen is highly reactive and can ignite or explode when it interacts with certain materials. Conventional lubricants may pose a significant safety risk due to their potential flammability and reactivity with hydrogen. In contrast, hydrogen-safe lubricants are engineered to mitigate these risks with low flammability and high chemical stability, making them ideal for hydrogen applications.
Beyond safety, these lubricants also enhance equipment performance and longevity. They provide excellent thermal stability, oxidation resistance, and wear protection, reducing the frequency of lubricant changes and lowering operational costs.

Benefits of Using Krytox Lubricants on Valves:

  • Nonflammable
  • Non-reactive with aggressive chemicals
  • Excellent compatibility with gasket, seal and O-ring materials
  • Noncorrosive towards common valve constructions
  • Insoluble in aqueous solutions, fuels, and common solvents
  • Resists oxidation and degradation
  • Non-volatile
  • Undamaged by steam, moisture, and pressure
  • Maintains lubricity/viscosity in a wide range of temperatures
  • Minimal environmental footprint – chemically/biologically inert and silcone-free
  • Prevents seizing and corrosion
