Proper Installation of an O-Ring: Standard Male Gland

Typically when installing an O-ring into a standard male gland, the process is pretty straight forward. Guide the O-ring along the shaft until you reach the gland to where it snaps in place. Sounds simple enough, but here are some tips on exactly what to do, and not to do.

Installation steps

  1. If it’s required for the seal to pass over threads, try to cover the threads as fully as possible. If an O-ring is slid or pushed over threads, there is potential for the rubber to be cut, rendering the seal useless. A light layer of lubrication can also aid with passing over threads.
  2. Though it may seem like the easier way to get the O-ring installed, make sure not to roll the O-ring down the shaft. Doing so will ensure that the O-ring is not installed in a spiral state. Spiral wound O-rings can lead to premature mechanical damage and or leakage. Once again, a light film of lubrication can assist in avoiding rolling the O-ring.
  3. Lastly, when assembling the fixture, make sure the female portion has a radius on the corners and a lead in the chamfer. This will help avoid mechanical damage to the seal upon assembly.

For more information refer to the Parker O-Ring Handbook. This book contains extensive information about the properties of basic sealing elastomers, as well as examples of typical O-ring applications, fundamentals of static and dynamic seal design and O-ring failure modes. It also provides an overview of international sizes and standards, and compatibility data for fluids, gases and solids.
