Types of O-Rings for Mechanical Keyboards
Mechanical keyboards are loved for their tactile feedback and sound. However, the click-clack noise can sometimes be overpowering, especially in professional or shared space. Fortunately, there are O-rings, small rubber pieces, that dampen your keyboard’s sound without taking away the tactile feel. There are several types of O-rings including silicone, rubber, nitrile, and vinyl. Each type has its characteristics, advantages, and drawbacks, which we will discuss in detail.
Silicone O-rings are a favorite among keyboard enthusiasts. They resist heat better than most other materials and have superior flexibility. Silicone rings are soft but sturdy, offering silent typing with excellent tactile feedback. Moreover, they don’t deform or harden over time and are not affected by UV rays or ozone. However, they are costlier and more sensitive to tearing.
Rubber O-rings are among the most common. They are cost-effective and widely available. They possess excellent compression set, resilience, and tensile strength. Furthermore, they provide a soft landing, reducing the keystroke sound efficiently. On the downside, they may harden and lose flexibility over extended use.
Nitrile O-rings offer a compelling balance between durability, chemical resistance, and noise reduction. Besides, they perform exceptionally well in a wide variety of temperature ranges and maintain their elasticity better in comparison to other varieties. However, they may deteriorate quicker when exposed to UV and ozone.
The vinyl O-rings have high chemical resistance and excellent performance in a wide temperature range. Additionally, they are less prone to wear and tear. Nevertheless, they may lack the natural softness needed for comfortable typing and might not efficiently dampen the keystroke sound.
O-Ring Hardness
O-rings hardness matters since it impacts the typing feel and sound dampening effect. O-rings hardness is measured in durometers, with the common ones being 40A, 50A, 70A, and 90A. Soft O-rings (40A-50A) provide a bottom out cushion, changing your board’s feel significantly. They tend to quieten the noise more effectively, but the reduced travel can be off-putting for some. Hard O-rings (70A-90A) let you preserve most of your key travel while still minimizing bottom-out noise.
O-Ring Thickness
You must also consider O-ring thickness. Thick O-rings reduce the key travel significantly, leading to a ‘mushy’ typing feel, but better noise reduction. On the other hand, thin O-rings minimize noise without shortening key travel too drastically. The thickness you select, therefore, depends mostly on whether you value quietness or key travel.
Color and Size of O-Rings
O-ring color is a mainly aesthetic concern. O-rings are typically concealed under keycaps and thus don’t affect your keyboard’s appearance. But if you want a matching or contrasting color for particular aesthetic reasons, there are numerous color options available, including red, blue, black, and clear transparent.
Size is another factor to observe. Most mechanical keyboards use Cherry MX switches or their clones, which fit perfectly with an O-ring diameter of 5mm (outside) and 2mm (inside). However, always check your keyboard’s specific requirements before purchase.
Installation of O-Rings
Installing O-rings on your keyboard requires some level of patience and precision. Different keyboards have different keycap removal processes. Therefore, you will need to research and understand your keyboard’s mechanism. After successfully removing the keycaps, you can quickly insert the O-rings on the underside. A keycap puller and O-ring applicator can make the process much smoother.
Conclusion
In conclusion, choosing the best O-rings for a mechanical keyboard largely depends on subjective preferences and the specifics of your keyboard. Start by understanding the different types of O-rings, their hardness, and thickness. Then consider the color and size that suit your aesthetics and keyboard requirements, respectively. Lastly, familiarize yourself with the installation process to ensure correct fitting and maximum effectiveness.
