FLUOROLUBE Oils - PCTFE Fluoropolymer Oil - Flame Resistant Corrosion Resistant Long Lasting Lubricants

Fluorolube® Oils are high-density, nonflammable PCTFE (polychlorotrifluoroethylene) lubricants engineered for extreme chemical stability and performance in aggressive environments.  These fluids are widely used where conventional hydrocarbons, silicones, or PFPEs fail—particularly in strongly oxidizing, acidic, or oxygen-rich systems. 

Unlike many specialty lubricants, Fluorolube oils combine chemical inertness, low vapor pressure, high density, and broad viscosity availability, making them suitable for applications ranging from precision instrumentation to vacuum systems and oxygen service.

Why Choose Fluorolube Oils?

• Chemically: ~80% combined fluorine + chlorine

•  

  Nonflammable (no flash point)

•  

  Stable in aggressive chemical environments

•  

  Nonflammable fluoropolymer fluids

• Exceptional chemical resistance

• Stable across extreme temperatures

• Available in wide viscosity range (6 → 1400 cSt)

• Ideal for oxygen service, vacuum systems, and aggressive chemistries

FLUOROLUBE oils deliver long-lasting lubrication for metals and metallic surfaces in hazardous operations.  Fluorolube excels in extremely harsh acidic, hot, flamable, explosive and/or oxidizing environments. 

These PCTFE fluropolymer oils are clear, colorless, fluorinated, synthetic, non-reactive, non-flammable, stable in chemical and oxygen services and environments, fully saturated, hydrogen-free, low-molecular-weight oils made from Chlorotrifluoroethylene Polymer (PCTFE). Fluorolube combines high-temperature performance, non-flammability, and chemical inertness under many demanding conditions.

Available in a range of viscosities, FLUOROLUBE^® oils are compatible with chlorine, oxygen, hydrogen peroxide, red fuming nitric acid and other strong oxidizing agents, and are nonflammable.

Fluorolube Oil Grades – Viscosity & Physical Properties

Fluorolube Oil Selection Guide

(Functional View, what the data means)

Thermal Stability

• Fluorolube Oils are sable from ~300°F to 600°F (150–315°C) depending on exposure conditions
• High temperatures can cause controlled depolymerization into volatile fragments
• Performance depends on metal contact and exposure duration

Thermal stability depends on the duration of heating and the materials of construction. Exposure to high temperatures will cause these products to depolymerize to lower molecular weight volatile compounds.  Thermal stability is affected by the presence of metals. High temperature uses of approximately 300°F (150°C) should be evaluated before field application.  FLUOROLUBE® Oils consist of about 80% combined fluorine and chlorine and are nonflammable.

Fluorolube Oil Behavior vs Temperature 

All Fluorolube oils:

• • Decrease in viscosity as temperature increases
  • Maintain lubricating film at high temperatures
  • Remain flowable at low temperatures (grade dependent)

Relative Behavior by Grade:

Chemical Resistance

Fluorolube oils are highly resistant to:

• Strong acids
• Oxidizers
• Halogens (chlorine, fluorine environments)

And have great compatibility with:

• Chlorine systems
• Oxygen systems
• Hydrogen peroxide processes

Vapor Pressure & Vacuum Performance

• Extremely low vapor pressure across temperature range (see chart, page 10 of product brochure for more detail)

Density (Important Differentiator)

• Much higher than hydrocarbons: ~1.86 to 1.96 g/cc
• Enabling Better sealing, Improved film persistence, and Reduced volatility

Electrical Properties

• Typical resistivity: 10¹³ to 10¹⁴ ohm-cm
• Useful for: dielectric fluids, electronics, instrumentation

CRITICAL LIMITATIONS (Important Read)

Reactive Metal Warning:  Do NOT use with Aluminum or Magnesium when in an environment of High load, High friction, or Confined environments

Risk: detonation or violent reaction

Do not use on copper, aluminum or magnesium parts when heavy friction or galling are possible. 

Detonation can occur when FLUOROLUBE® Oils are allowed to contact these reactive metals free of their oxide coating in confined spaces and under heavy loads or high pressure.

FLUOROLUBE® Oils may react violently with sodium and potassium metals, amines, hydrazine, liquid fluorine and liquid chlorine trifluoride.
