How does installing an O-ring on a mechanical keyboard affect it?


In the world of mechanical keyboards, enthusiasts are always on the lookout for ways to enhance their typing experience. One popular modification is installing o-rings on the key switches. But what exactly is an o-ring, and how does it affect the mechanical keyboard’s performance? In this article, we will explore the impact of installing o-rings on a mechanical keyboard and delve into the advantages, potential drawbacks, and the overall effect on typing feel. Whether you are a seasoned mechanical keyboard user or a newcomer, this comprehensive guide will provide you with valuable insights and actionable tips.

Understanding O-Rings

An o-ring is a small, circular rubber ring designed to dampen the sound and reduce the travel distance of the mechanical key switches. It fits around the keycap stem and acts as a cushion when the keycap hits the switch housing upon keystroke. The primary purpose of installing o-rings is to reduce noise and create a softer, more cushioned feel during typing.

The Impact on Typing Sound

One of the most significant advantages of installing o-rings on a mechanical keyboard is the substantial reduction in typing noise. Mechanical keyboards are known for their satisfying tactile feedback and audible clicky sounds, which can be a delight for some users but a nuisance for others, especially in shared workspaces. Adding o-rings dampens the clack of the key hitting the switch housing, resulting in a much quieter typing experience.

The Effect on Key Travel Distance

The key travel distance refers to the distance a key must travel down to register a keystroke. Some mechanical keyboards have a relatively long key travel distance, which can lead to finger fatigue during extended typing sessions. Installing o-rings shortens the key travel distance by creating a cushioning effect when the key reaches the bottom, allowing for quicker keystrokes and potentially reducing the strain on your fingers.

Compatibility with Keycap Profiles

One factor to consider when installing o-rings is their compatibility with different keycap profiles. Some keycap sets may not sit well with o-rings, resulting in an unsatisfactory typing experience. Researching and choosing o-rings that complement the keycap set used on the mechanical keyboard is essential to ensure a seamless fit and consistent typing experience.

Installation Process and Tips

The installation of o-rings on a mechanical keyboard is generally straightforward and can be done without professional assistance. Here’s a step-by-step guide to help you through the process:

  1. Remove the Keycaps: Carefully remove the keycaps from the mechanical keyboard using a keycap puller or a wire keycap puller. Gently wiggle the puller to dislodge the keycap from the switch stem.
  2. Clean the Keyboard: Take the opportunity to clean the keyboard thoroughly, removing any debris or dust that may have accumulated over time.
  3. Install the O-Rings: Place the o-rings around the switch stem of each keycap. Ensure that they are aligned properly to avoid any interference with the keycap mounting.
  4. Reattach the Keycaps: After installing the o-rings, carefully reattach the keycaps to their respective switches. Press down firmly until they click into place.
  5. Test and Adjust: Test the keyboard after installation to check for any unintended issues. Some users might prefer to adjust the o-ring thickness to achieve the desired level of cushioning and feedback.

Pros and Cons of Using O-Rings on Mechanical Keyboards

Let’s explore the pros and cons of installing o-rings on a mechanical keyboard to help you make an informed decision:


  • Noise Reduction: O-rings significantly reduce the clack sound, making the keyboard quieter and more suitable for shared environments.
  • Shorter Travel Distance: Typing with o-rings can result in shorter key travel, potentially leading to faster typing speeds and reduced finger strain.
  • Customizable Tactile Feel: Depending on the o-ring thickness, users can adjust the tactile feedback to suit their preferences.


  • Altered Typing Feel: Some users may find that the o-rings change the keyboard’s overall feel, impacting the satisfying tactile experience.
  • Incompatibility with Keycaps: Certain keycap profiles may not work well with o-rings, leading to poor fit and performance.
  • Learning Curve: It may take some time to adjust to the new typing feel with o-rings, especially for seasoned mechanical keyboard users.

Frequently Asked Question (FAQs)

Q: Do o-rings fit all mechanical keyboards?

A: O-rings are generally compatible with most mechanical keyboards, but checking the keycap profile and switch type is essential for optimal performance.

Q: Can I remove the o-rings if I don’t like them?

A: Yes, o-rings can be removed if you find that they don’t suit your typing preferences. However, it’s best to store them properly in case you decide to use them again later.

Q: Are o-rings difficult to install?

A: No, the installation process is relatively simple and can be done by following the provided instructions. It does not require any technical expertise.

Q: How do I choose the right o-ring thickness?

A: The ideal o-ring thickness depends on personal preference. Experiment with different thicknesses to find the one that suits your typing style best.

Q: Can I use o-rings on gaming keyboards?

A: Absolutely! O-rings can enhance the gaming experience by reducing noise without compromising the quick response and actuation times.

Q: Do o-rings affect the durability of the keyboard switches?

A: Properly installed o-rings should not significantly impact the durability of the switches. However, using low-quality or incorrectly sized o-rings could cause issues over time.


Installing o-rings on a mechanical keyboard can significantly affect the overall typing experience. While they excel at reducing typing noise and shortening key travel distance, users should also consider the impact on tactile feedback and typing feel. Before making a decision, try out different o-ring thicknesses and evaluate how they align with your preferences. Remember that the typing experience is subjective, and what works well for one person may not be ideal for another. As with any modification, choose high-quality o-rings, and if they don’t suit your needs, feel free to remove them and explore other ways to personalize your mechanical keyboard.
