For these applications we developed more viscous, high temperature, deep vacuum, oils and called them TLC 13 and TLC 15. The numbers 13 and 15 correlate to their vapor pressure at 40 C.

• TLC 13 has an estimated useful range of -17.6 to 675 F.
• TLC 15 has an estimated useful range of -1.4 to 689 F.
• Temperature – TorrLube lubricants can handle very high temperatures.
• Low Vapor Pressure – TorrLube lubricants have very low vapor pressure.
• Lubricity – TorrLube is an excellent lubricant under both atmosphere and vacuum.
• Nonflammable – TorrLube lubricants do not ignite.
• Non-Reactive – TorrLube lubricants are inert and do not react with most materials used in Semiconductor or Aerospace industries.
• Chemical Resistance – TorrLube lubricants are resistant to most chemicals used in both Semiconductor or Aerospace industries.
• Safe in Oxygen Service –TorrLube lubricants do not react with oxygen. 
• Low Outgassing – TorrLube lubricants display very low outgassing.
• O-Ring Conditioning – Conditioning O-rings with TorrLube lubricants will enhance the surface of the O-ring making it less permeable and more supple, providing a better seal and extending uptime.
• Shelf Life – TorrLube lubricants have infinite shelf life.
