Krytox™ GPL 221 Grease | Anti-Corrosion General-Purpose Lubricants
Sodium Nitrite Additive,100% Nonflammable
The Krytox GPL 221 grease contains an anti-corrosion/anti-wear inhibitor and is ideal for corrosive environments where there is no danger of the sodium nitrite additive reacting with chemicals or causing contamination problems. Typical applications are automotive bearings, sealed pump bearings, electric motor bearings, and general-purpose bearings. Krytox oils and greases are silicone-free. They do not contain any VOC materials or chlorine and are not hazardous to the atmosphere or ozone layer. They are biologically and environmentally inert.
The fully fluorinated Krytox GPL 221 high-temperature stability provides bottom-line savings from improved reliability and a reduction in grease usage and manpower through extended relubrication intervals. Excellent film strength reduces wear to reduce maintenance costs. Under high loads the viscosity increases to provide support and absorb the pressure.
Why Krytox GPL 221?
Krytox lubricants provide longer-lasting lubrication that reduces the frequency of re-lubrication, not only reducing operating costs, but also reducing waste and potential impact on the environment. Krytox lubricants are undamaged by, and non-reactive with, acidic or caustic cleaners and disinfectants, steam, moisture or high temperatures. The original properties of the fluids can be restored through regeneration; thus, reducing or minimizing disposal and incineration. Chemours has a regeneration program that reclaims PFPE fluid. This lowers the overall cost of the fluids, and reduces or minimizes safety and environmental disposal problems. For applications that require no additives, we recommend Krytox™ GPL 10X Oil, or Krytox™ GPL 20X Grease
