Don’t Forget About the O-Ring!

First, what is an O-ring? An O-ring is a doughnut, or torus shaped seal typically used to prevent the passing of air or fluid. O-rings are used to keep fluid or air IN or OUT of a defined space. This device helps to keep the water tight or air tight integrity of a filter housing or filter application. O-rings come in a wide variety of sizes and different types of materials; Types of Material

  • Buna-N®
  • Ethylene, Propylene
  • Silicon Encapsulated with FEP, an FDA-approved material
  • Silicone (Solid)
  • Teflon® (Solid)
  • Teflon® Encapsulated with FEP
  • Viton® (Solid)

    To extend the o-ring’s effectiveness there are some things you can do: Remove and inspect the o-ring at every filter change or every time the housing is opened, as well as applying the manufacturer’s approved lubricant. The protectant/gel, usually made of silicon is inexpensive and is easy to apply. If there are signs of any wear or improper form of the o-ring, the o-ring must be replaced immediately prior to restarting the filter system.    The life of an o-ring varies based on how you take care of it and what it is made of. It is very important to your operation to make sure you have the proper o-ring for your filtration application.
