Krytox® Corrugator Greases

NSF H-1 FOOD GRADE CERTIFIED
Krytox® – Setting the Standard for the 
Corrugating Industry
Since the 1980s, Krytox® anticorrosion greases have set the 
standard for high temperature bearing lubrication in corrugator 
applications. These products are the same high performance 
formulation the corrugated industry has trusted for years, and 
we are pleased to announce, are now certified for incidental 
food contact.
NSF Certification Means Safety and Confidence
To provide absolute confidence and safety in food related 
operations, these products are NSF H-1 Food Grade certified.
Corrugator Krytox® 226 FG and Corrugator Krytox® 227 FG 
provide you with peace-of-mind and full confidence that 
Krytox® greases are non-toxic, and completely biologically and 
environmentally inert.
Krytox® corrugator greases are recommended for use in 
high temperature corrugated equipment applications and in 
manufacture of food packaging materials where an H-1 rated 
lubricant is required. 
Reliability and Performance for Your 
Most Demanding Needs 
High temperature, extreme pressure Krytox® greases excel in 
the most demanding environments. Their non-oxidizing 
chemistry and wide temperature range allows them to be used 
in temperature extremes. Its superior oil film strength reduces 
friction and abrasive wear to significantly extend equipment life 
in severe duty applications. Krytox® provides excellent water 
washout resistance and superior rust and corrosion protection 
for bearings and components. Krytox® is silicone-free, contains 
no VOC materials or chlorine, and is not hazardous to the

Chemical and Environmental Compatibility
While Krytox® fluorinated greases are non-reactive, its PFPE 
chemistry is very different from standard hydrocarbon or 
synthetic chemistries and should never be mixed with 
non-fluorinated greases. 
Krytox® lubricants are inert and will not react with any materials 
they may come in contact with. The polymeric nature of these 
products is extremely resistant to moisture, so it stays in place 
during cleaning. Cleaners and disinfectants, both acidic and 
caustic types, do not affect them. Steam and high temperatures 
will not damage them. They do not damage plastic or elastomer 
seals or cause corrosion to metals. They are nonflammable and 
are safe for use in oxygen service. 
Packing the Bearing
New bearings should be inspected for damage and cleanliness 
before use. New unlubricated bearings are often coated with 
hydrocarbon based rust preventive oils to protect them during 
storage. These preservative oils must be removed when using 
Krytox® as a lubricant. Failure to do so could result in reduced 
bearing life. 
The preservatives coat the bearing surface to prevent rust and 
corrosion, but if not removed prior to use will prevent the grease 
from protecting the metal surface. If left on the bearing, the 
preservative coating can oxidize and harden, and can create 
debris that will contaminate the grease.
Storage and Shelf Life
Krytox® grease and oil lubricants have no expiration date, and 
have an indefinite shelf life if unopened and stored in a clean 
dry location.
