Krytox 205 g0 Switch Lubricant

Product Information

When lubing many switches at a time, you might want to gather all your springs and a pea size dollop of Krytox 205 grade 0 in a container or an inflated baggy. Then shake real good for a couple minutes--it's called bag-lubing and will evenly coat your springs with Krytox 205 grade 0. While Krytox™ grease will not react with the other greases or cause decomposition or any hazardous reactions, it will not stop the other lubricant from breaking down from heat and oxidation. Therefore, it is not recommended to mix Krytox™ lubricants with any non-perfluoropolyether (PFPE) oil or grease. Characteristics of Krytox™ Performance Lubricants The thing to remember is that evenness is the name of the game when lubricating your switches with 205 grade 0. It's always easier to add lube than to remove lube, so don't hesitate to experiment with different amounts of 205g0 on a few of your switches to find out what you like best. Once you've found out, rinse and repeat, consistently. Tips on Using Krytox 205 Grade 0 effectively In time, Krytox GPL 205 grade 0 tends to separate slightly--you'll see a little coat of oil on top of the 205G0 grease. This is why you always want to shake well or mix your Krytox 205 grade 0 on a palette to give it its best integrity.

I heard about very popular one called Krytox. The most talked about are Krytox GPL 205g0, GPL 205g2 and GPL 105g0. So what do these grades mean and which one is the best for linears? What are your recommendations? The Krytox™ GPL 22X series contains sodium nitrite corrosion an anti-wear inhibitor; it also improves load-carrying performance and is ideal for corrosive environments. Typical applications are automotive bearings, sealed pump bearings, electric motor bearings, and general-purpose bearings. Practice makes perfect, so don't be too harsh on yourself if you don't manage to have evenly lubed switches (or keyboard stabilizers) on your first attempt. And so you know, over time and use, Krytox 205 grade 0, and lubricants in general, will distribute itself where it needs to go inside the switch.Switch lubricating can sound scary but in reality is quite simple and makes a huge difference in both feel and sound! Lubricant can not be cleaned with soap and water and is resistant to many solvents. Although the lubricant is chemically stable and non-hazardous please wear gloves and place a protective layer of drop-plastic below any working surface. Spills are difficult to clean, and the lubricant will transfer from an operators hands to any surface they may touch. Please clean up any accidents with a microfiber cloth. Certain switches have more stem wobble and looser housings than others--you might want to add switch films to help with these issues during your lubing process. If you are going to build more than one keyboard or you have a hot-swap PCB and want to swap your switches regularly, get a lubing station. It will help you be more efficient and organized.

Krytox™ lubricants can be used in applications where nonflammability, oxygen compatibility, materials compatibility, high-temperature stability, and resistance to aggressive chemicals are requirements. Industries include: Krytox™ lubricants have become the product of choice for a wide range of applications, where extremely high- or low-temperature performance, nonflammability, longevity, oxygen compatibility, and resistance to aggressive chemicals are required. As a general rule of thumb, lower viscosity lubricants are used on tactile switches, whereas higher viscosity lubricants are used on linear switches. This is often desirable because you don’t want to cover up the tactility of a tactile switch. You want to keep that exposed while smoothing away some imperfections. On the other hand, a linear switch may not have as much character as a tactile switch and perhaps you might feel the imperfections a bit more as well, and so often you want a very smooth experience while not worrying too much about masking the original switch qualities.

Greases can be formulated with different viscosity oils to handle varying temperatures and load conditions. Independently tested and confirmed for LOX and GOX use by major oxygen manufacturers and test authorities, including BAM.

Different Krytox™ oils have specific properties that make them well-suited for the demands of particular industries or environments. The family of Krytox™ oils includes: Don’t overthink it. I believe many of us get caught up in the right or wrongs inherent of this community but a lot of it is really subtle differences that quite frankly you might not notice when typing daily. I’m all for paying attention to the details (hence my own journey into the lube world) but don’t feel obligated to use this or that just because so and so says so. Honestly, it’s pretty hard to screw this up so long as you’re using one of the above mentioned lubricants. One thing I will say that might sway you in one direction over the other is that oil is a bit more versatile than grease when it comes to application methods. Oil can be brushed onto the housing and stem but can also be used more easily when bag lubing springs (I will go over this later). Grease, on the other hand, is easy to apply by brush to the housing and stem but may be more difficult and time consuming to apply to springs as you then have to brush a bit of grease onto each spring individually. Let’s start with why we lube switches. Often a switch will come prelubed from the factory but only with a small amount that is sloppily applied to the stem legs. This may be all fine and well for the uninitiated but if we’re going to take the time to build a custom board we may as well do it right.

The scariest thing about Apple’s announcement

You’ll notice that I specified just the switch housing and stems. The spring is a whole other matter. Personally I have found that a heavier lubricant is preferable to dampen any spring noises but just about anything can be used. When in doubt, or if the budget is tight, or if it’s just more readily available, the xx4 viscosity is a good overall choice. Also keep in mind, how much you apply, and where you apply can greatly affect the final feeling too. Which brings us to our next point… How do I use these dang lubes?

Krytox™ performance lubricants are not only resistant to oxygen and reactive gases, but they are also inert to virtually all chemicals commonly used in most industries. For further information, please refer to Krytox™ Lubricants: Chemical Stability or Gas Compatibility. If your grease is whitish in colour a good rule of thumb is that you’ve used too much if you can tell that it is white when you apply it to the switch. In thinner applications it should be fairly clear. Before adding Krytox™ grease, bearings should be cleaned of all existing greases, oils, or preservative oils used during storage. If non-perfluoropolyether (PFPE) oils or greases are left in a bearing, they can form carbon deposits at high temperatures, which may accelerate bearing failure.Additives are often incorporated into the grease to enhance anti-corrosion protection and raise load-carrying ability, reducing wear. Our standard grease grade is NLGI (National Lubricating Grease Institute) Grade 2; however, upon request, we produce NLGI Grades 000 through 6. For more information on NLGI grade options, please refer to the Krytox™ Performance Lubricants Product Overview. Honestly, if it’s easier to get one over the other then don’t fret too much about it. What’s with all the Numbers? DuPont only manufactures Krytox in China, and has not manufactured any Krytox products in the United States in decades. I cannot say if it is the same [as Miller-Stephenson] or not, but I can say if it is crossing markets it is definitely gray market, which is generally not allowed, or very very old. Lubricating switches can help dampen sounds both from the housing and stem itself but also from the spring. It can smooth out imperfections in the material and help things glide along with less friction and hitches. It can do this without removing tactility if done properly and with the right lube (more on this later) and it can also take a decent linear switch into buttery smooth heaven.
