From the manufacturer

Krytox High Performance Synthetic Lubricants

Premium grease and oil for bearings, valves, seals, and other applications over a wide temperature range and under extreme conditions

Krytox High Performance Synthetic Lubricants

Extreme Conditions Require Extreme Performance

Krytox oils and greases are based on perfluoropolyether (PFPE) oils. This series of synthetic fluorinated lubricants are used in extreme conditions, such as high temperatures up to 204 °C (400 °F), and will survive short-term peak temperatures of up to 220 °C (429°F). Chemically inert and safe for use around hazardous chemicals, these lubricants are nonflammable and also safe for use in oxygen service. Krytox oils and greases do not damage plastics or elastomers, nor cause corrosion to metals. They are commonly used as lubricants in aerospace, automotive, industrial, and semiconductor applications, as well as in solving many other routine lubrication problems. In addition, they provide exceptionally long lifetimes in sealed-for-life bearings and extend re-lubrication intervals in bearings that require re-lubrication.

Biologically Inert While Retaining High Temperature and Pressure Stability

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 high-temperature stability provides bottom-line savings from improved reliability, and a reduction in grease usage and manpower through extended re-lubrication intervals. Excellent film strength reduces wear to reduce maintenance costs. Under high loads, the viscosity increases to provide support and absorb the pressure.

A Multitude of Applications

For those who regularly manage lubrication issues, every day is a fight against the forces of excess friction, vibration and wear. Krytox oils, greases and solvents offer advanced lubricant solutions for a broad variety of industrial applications including: bearings and sintering bearings, electric motors, functional fluids, gearboxes, extreme temperatures, o-rings, seals, and valves.

Krytox Performance Lubricants are:

  • Formulated for many applications and industries
  • Able to help increase maintenance intervals
  • Highly stable in extreme conditions
  • Chemically inert
  • Insoluble in water
  • Safe for seals and bearings
  • Non-flammable
  • Long-lasting, needing less re-lubrication so you’ll use less
  • Nontoxic and NSF H1-certified for food use
  • Can be regenerated

Some of Krytox's Most Popular Formulas

Krytox GPL 105 and 106 Oils

Krytox GPL 105 and 106 oils are a clear, colorless, fluorinated synthetic oil that is non-reactive, nonflammable, safe in chemical and oxygen service, and are long lasting.

Krytox GPL 205 and 206 Greases

Krytox GPL 205 and 206 greases are PTFE thickened, contain no additives, and can be used on components that come in contact with chemicals. Typical applications include valves, instruments, or bearings in contact with chemicals, including alcohols, ammonia, solvents, steam, acids and bases, and oxygen systems, including LOX and GOX. They are commonly used as seal and o-ring lubricants, and are compatible with all types of seals.

Krytox GPL 215 and 216 Greases

Krytox GPL 215 grease contains molybdenum disulfide for extreme pressure (EP) conditions and should be used for slow speed or heavily loaded applications, where there is no danger of the molybdenum disulfide additive reacting with chemicals or causing contamination.

Krytox GPL 225 and 226 Greases

Krytox GPL 225 and 226 greases contain 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.

    Expensive but your only option

    Expensive but your only option
    Many may shiver while buying this as it is not the world known 205 G0 but I assure you it sounds just as good. I used this for a budget build with gateron yellows, when I say I am amazed I truly am, this lubricant is a miracle worker they took the feeling and sound from meh to holy crap (for sound I also recommend filming the switches as it highly improved my sound and was dirt cheap). I would say this is highly over priced at $20 for a spit and a lick but honestly this is your only option. I used about 1/5 or so of the smallest tube to lube about 60 or so keys so give or take 300+ keys. This won’t be lasting forever but certainly is enough to get the job done. 10/10 would recommend and buy again once you get by the price it’s honestly a need.

    I used this to lubricate the seal on my 2015 F150 sunroof, which was sticking and causing damage to the plastic sunroof components. Once I lubed the spot that was sticking toward the back of the glass, all the stickiness went away and the sunroof opened better than ever (after I replaced the broken plastic bits that is).

    Expensive, but worth it. You don't need very much. I keep the tube in my truck and hit the sunroof with a little bead a few times a year.

    5.0 out of 5 stars Alfa Romeo Sunroof Application
    Reviewed in the United States on December 2, 2023
    Size: 0.5 ozStyle: Krytox GPL205 Performance Lubricant GreasePattern Name: GreaseVerified Purchase
    This product did absolute wonders on a creaky sunroof in my Alfa Romeo vehicle. Applied to the sunroof rails, seal/gasket, and anywhere a touch-point with the glass made contact.

    Prior to application, the sunroof would make a creaking noise almost to the point that I thought my glass was shattering due to the noise. After application the once cringe-worthy noise was gone. I am completely blown away and it's almost as if I'm driving a different vehicle due to the peace of mind I now have.

    I used almost the entire tube, I have some left over in the chance I need to make any minor additions later on. Likely has to be re-applied every six-months/season.

    5.0 out of 5 stars Used to lubricate Cherry MX Silent Reds (Pink) Switches
    Reviewed in the United States on August 18, 2020
    Size: 0.5 ozStyle: Krytox GPL205 Performance Lubricant GreasePattern Name: GreaseVerified Purchase
    I was looking for Krytox 205g0, but I have had the hardest time finding it, so I decided to give this 205g2 a try.

    I used these to lubricate Cherry Silent Reds, aka Pinks. If you all are familiar with Cherry switches, they are VERY scratchy. And with the Silent Reds, the scratchy sound is very pronounced because the rest of the switch is so quiet. Not only can you hear the scratch, but you can actually feel it through your fingertips.

    Since this is 205g2 and a lot thicker than 205g0, I decided to be VERY conservative in my application. For perspective, 205g2 has a consistency/viscosity akin to Neosporin on a cold morning.

    I got the 0.5 oz tube. After fully lubricating my 60% keyboard, I used maybe 0.1oz. Yes, I still have more than 80% of the tube remaining.

    How I applied the lube? I used a fine brush. I put enough lubricant on the brush to get the brush shiny, with no lubricant visible other than the sheen of the brush. I brushed the base rails and spring holder. I brushed the spring. I brushed the stem rails and switch actuator prongs.

    So what were the results? Simply Amazing! This is now the quietest keyboard I have ever used. Every once in a while, I hear a very subtle thock every once in a while when I bottom out a key, especially the space bar. But the thock is subdued by the Silent Reds, and it's such a pleasing sound...think ASMR. The biggest concern I had with using this lubricant was that the keys would become sluggish, as it is thicker than I wanted. With my very conservative application, I am experience no sluggishness or resistance. Keys are popping back up as fast as I need them to, and there is no mushiness.

    From one keyboard enthusiast who used a VERY conservative amount of this lubricant on my Cherry Silent Reds(pink) switches, I can tell you...get this lubricant if you are needing some high quality dielectric lubricant for your switches. I am confident that I could lubricate FIVE 60% keyboards with just a 0.5 oz tube. That's 4 dollars of lubricant per keyboard at current prices. Well worth it in my opinion. I couldn't be happier. I am currently using my freshly lubricated keyboard to write this review, and I have never been so satisfied typing.
