Krytox GPL-104 PFPE Lubricating Oil, 1.1 lb
Krytox GPL-104 PFPE Lubricating Oil, 1.1 lb
Krytox GPL-104 is a clear, colorless synthetic perfluoropolyether (PFPE) lubricating oil for industrial equipment requiring a chemically stable fluid lubricant. This 1.1 lb package supplies GPL 104 grade oil with a typical viscosity of 60 cSt at 40°C and an estimated useful temperature range of −51 to 179°C (−60 to 355°F). It is an oil, not a PTFE-thickened grease.
Best Uses / Applications
Consider GPL-104 for industrial maintenance and equipment applications where the specified lubricant is a PFPE oil of this viscosity. Krytox identifies GPL 104 as a compressor-oil option in its product guide. Equipment selection should account for operating temperature, lubricant delivery, speed, load and the equipment manufacturer's requirements.
- Compressor lubrication where the equipment specification calls for an appropriate PFPE oil.
- Industrial machinery requiring a fluid lubricant rather than a stay-in-place grease.
- Chemical-processing equipment where lubricant stability is an important selection criterion.
- Maintenance programs replacing the same specified GPL 104 grade.
Key Features
- PFPE chemistry: fluorinated synthetic oil designed for demanding industrial lubrication.
- Clear, colorless fluid: GPL 100–107 oils differ from the white, thickened GPL grease grades.
- Nonflammable oil: the manufacturer describes the GPL 100–107 oil family as nonflammable and non-reactive.
- Defined viscosity: 60 cSt at 40°C and 8.4 cSt at 100°C for grade-specific selection.
- Wide estimated useful temperature range: −51 to 179°C, subject to application conditions.

GPL 103 vs. GPL 104 vs. GPL 105 Oil
| Oil grade | Viscosity at 40°C | Viscosity at 100°C | Estimated useful range |
|---|---|---|---|
| GPL 103 | 30 cSt | 5 cSt | −60 to 154°C |
| GPL 104 | 60 cSt | 8.4 cSt | −51 to 179°C |
| GPL 105 | 160 cSt | 18 cSt | −36 to 204°C |
GPL 104 has a higher viscosity than GPL 103 and a lower viscosity than GPL 105 at the listed temperatures. Select the grade required by your equipment specification; a higher grade number is not automatically a better choice.
Frequently Asked Questions
What is Krytox GPL-104?
GPL-104 is a general-purpose PFPE synthetic lubricating oil. This listing is for a 1.1 lb package of GPL 104 grade oil.
Is GPL-104 an oil or a grease?
It is an oil. Krytox GPL 200–207 greases contain a PTFE thickener, while GPL 100–107 products are fluid oils. Do not substitute a grease for an oil solely because both carry the Krytox brand.
What is the viscosity of GPL-104?
Typical kinematic viscosity is 177 cSt at 20°C, 60 cSt at 40°C and 8.4 cSt at 100°C. The manufacturer's ISO viscosity grade is 68.
What temperature range does GPL-104 cover?
The manufacturer lists an estimated useful range of −51 to 179°C (−60 to 355°F). Actual suitability depends on equipment design and operating conditions.
How does GPL-104 compare with GPL-105?
GPL 104 is less viscous: 60 cSt versus 160 cSt at 40°C. GPL 105 also has a different estimated useful temperature range. Use your equipment requirements to choose between them.
Can GPL-104 be used as a compressor lubricant?
Krytox lists GPL 104 as a compressor-oil option in its product guide. Confirm that your compressor manufacturer specifies or approves this lubricant for the actual equipment and service conditions before use.
Does the 1.1 lb size describe volume?
No. It describes the package's net weight, not fluid ounces, container volume or packed shipping weight.
