What Type of O-Ring Material Is Right for My Application?
When it comes to choosing the right O ring material for your application, there are many factors to consider. Temperature range, chemical exposure, and abrasion resistance are just a few of the important considerations. This blog post will discuss the different types of O ring materials available and help you choose the right one for your needs.
Types of O Ring Materials
Many types of Orings materials are available on the market, each with its unique set of properties. The most common o-ring materials are:
Nitrile (Buna-N)
Nitrile is a synthetic rubber that offers excellent resistance to oils and chemicals. It has a wide temperature range (-40 to 212 degrees Fahrenheit), making it a good choice for many applications.
Viton
Viton is a synthetic rubber that offers excellent resistance to chemicals and high temperatures (up to 400 degrees Fahrenheit). It is not recommended for use in applications with exposure to petroleum products or other oils.
Silicone
Silicone is a synthetic rubber that offers excellent resistance to high temperatures (up to 400 degrees Fahrenheit) and has a wide temperature range (-103 to 500 degrees Fahrenheit). It is not recommended for use in applications with exposure to petroleum products or other oils.
EPDM
EPDM is a synthetic rubber with excellent chemical resistance and a wide temperature range (-55 to 300 degrees Fahrenheit). It is not recommended for use in applications with exposure to petroleum products or other oils.
PTFE
PTFE is a synthetic fluoropolymer that offers excellent resistance to chemicals and has a wide temperature range (-100 to 500 degrees Fahrenheit). It is not recommended for use in applications with exposure to petroleum products or other oils.
Urethane
Urethane is a synthetic polymer that offers excellent resistance to abrasion and has a wide temperature range (-60 to 200 degrees Fahrenheit). It is not recommended for use in applications with exposure to petroleum products or other oils.
How To Choose the Right O Ring Material
Now that you know the different types of o-rings available, how do you choose the right one for your application? Here are some factors to consider:
1. Temperature Range:
What is the temperature range of your application? You’ll want to choose an O ring material that can withstand the extremes of both hot and cold. You see, some materials can become hard and brittle in cold temperatures, while others may soften and lose their shape in heat.
If your application is exposed to both extreme temperatures, then you’ll need to choose a material that can handle both. On the other hand, if your application will only see one extreme temperature (either hot or cold), then you have a little more flexibility in your choice of material. But what if your application is going to see both high and low temperatures? In that case, you’ll need to choose a material that can handle both.
2. Chemical Exposure
Will your application be exposed to chemicals? If so, you’ll need to choose an O ring material compatible with the specific chemicals you’re using. Some materials are more resistant to certain chemicals than others.
3. Abrasion Resistance
Will your application be subject to abrasion? If so, you’ll need to choose an O ring material resistant to abrasion. Some materials are more resistant to abrasion than others.
Conclusion
Once you’ve considered all of these factors, you should have a good idea of which O ring material is right for your application. If you’re still not sure, don’t hesitate to contact us at Royal Brass Incorporated. We’re always happy to help.
