How To Install an O-Ring   

Once you have confirmed that your lubricant is safe for use with both your O-Ring and your application, it is a good practice to double-check the o-ring size. The wrong size can lead to a damaged seal, poor performance, or a damaged system.

Rubber o-rings are an essential component for a wide variety of fluid power applications. Even when you have a high-quality o-ring that is the appropriate size and material for the application, if it is not installed properly the seal can fail premature, which can lead to leaks and potential catastrophic system failure. There are important guidelines that should be followed to properly install an o-ring. It’s important to ensure that a seal is the right size and has been designed with the application in mind. Additionally, the seal should be well lubricated to make installation as simple as possible.

 

Three Steps To Installation

Step 1: Lubrication

Lubrication is highly recommended for o-ring installation. This is because a well-lubricated o-ring will reduce surface friction and create a smooth transition for installation. It is essential to choose the right lubricant and the proper formula will vary based on the type of application as well as the o-ring material. Take care to choose a lubricant that will work with your application and the o-ring.

 

Choosing a lubricant that is compatible with your O-Ring will ensure that it does not shrink or swell, which will influence how it performs once installed.

Step 2: Confirm Sizing

Once you have confirmed that your lubricant is safe for use with both your O-Ring and your application, it is a good practice to double-check the o-ring size. The wrong size can lead to a damaged seal, poor performance, or a damaged system.

 

 

Step 3: Installation 

Once you have verified the lubricant compatibility and size you are ready to place the o-ring. If necessary, during the installation process cover any sharp edges to avoid damage to the o-ring. Lightly lubricate the o-ring and place it in the groove, sliding it, not rolling it into place. In some instances, special o-ring tools can help to properly place an o-ring that cannot be easily placed by hand. A well-placed o-ring should be slightly stretched, with the stretch being between 1-5%, with 2% being ideal for most applications.
