## Overview

Captain O-Ring keyboard dampeners are precision-engineered EPDM rubber rings that reduce key travel by 0.2mm to significantly lower typing noise and finger fatigue. Designed to prevent the harsh 'bottoming out' sound of mechanical keyboards, this set includes 135 durable o-rings and a microfiber cleaning cloth for a complete upgrade. Easy to install and built to last, these dampeners transform your typing experience into a quieter, more comfortable workflow essential for professionals.

## Description

These Captain O-Ring keyboard switch dampener o-rings can be quickly installed on the stems of your keyboard keys to prevent keys from bottoming out. Bottoming out occurs when a key is pressed down to its limit, causing the key stem to collide with the switch casing. This results in a loud "clacking" noise while typing that affects virtually every mechanical keyboard. Captain O-Rings's keyboard dampeners provide a shock absorber at the bottom of each key to create a consistent, uniform sound while typing. These dampeners also reduce the travel of keys by 0.2mm, which greatly reduces finger fatigue. Durable EPDM rubber o-rings don't crack like black buna o-rings typically do in this application. To install, simply remove each key, place o-ring around the stem, and replace each key. Installation typically takes 4-5 minutes for the entire keyboard and lasts the life of the keyboard. What to expect: This item includes (135) keyboard o-rings and (1) Captain O-Ring screen cleaning cloth in a resealable zip-top poly bag with "Captain O-Ring" branded packaging. Manufactured and warrantied against defect for one year by Captain O-Ring LLC. "Captain O-Ring" is a registered trademark of Captain O-Ring LLC.
