What are Encapsulated O-Rings

When discussing the various o-ring options on offer, you might hear encapsulated o rings being discussed.

What is an Encapsulated O-Ring? 

An encapsulated o ring is slightly different to a typical o-ring, as it’s created with an elastomer stimulating core. It has a seamless shield that is made from Fluorinated Ethylene Propylene or Perfluoroalkoxy, both of which are chemical-resistant materials. They help to prevent corrosive fluids and gasses from getting into the elastomer during any type of application. Although it is often known as an elastic o-ring, it’s important to note that encapsulated o-rings aren’t elastomers. They are made from plastic but still offer the same characteristics as rubber and elastomers. The shield is hard, but the core elastomer provides the memory of the o-ring when it’s placed under pressure. It, therefore, offers unique properties and advantages when compared to typical o-rings, which is why more businesses are opting to use this solution.

What Does an Encapsulated O-Ring Look Like? 

The common profile of an encapsulated o-ring will be a circular cross-section, however, you can request oval, square, or rectangular shapes ones. These will naturally be more expensive, which is why they are less commonly used. A lot of tools and time are needed for this option, so it is a complex solution which only specialists in the field will offer. Encapsulated o-rings can be offered in a variety of thicknesses, and these products are offered tailored to a client’s needs. Most companies will offer a variety of sizes as standard, which are the most popular dimensions based on their experience and clients. This will help you find a solution quickly when needed and offer a more cost-effective solution for every client.

The minimum inner diameter will depend on the thickness of the o-ring. However, there’s no maximum size when it comes to the inner diameter. Some o-rings on offer are slightly compressible, which will help to fit the space they are getting used in. As you can see, they offer many design benefits over typical o-rings, which is why we recommend considering this type of o-ring for certain projects.

The Advantages of Encapsulated O-Rings 

There are many great benefits of investing in encapsulated o rings, including low contamination and low penetrability. The ratio of friction is between just 0.1 and 0.2, which is much lower than other options. They are compliant with many industry regulations, so you’ll have a safe and secure solution to use on a regular basis. Encapsulated o-rings can be used at a wide range of temperatures, and they are resistant to nearly all media. We find they are particularly useful for businesses operating within the chemical processing, food, and pharmaceutical industries. For these businesses, they will be a cost-effective solution that offers high-performance levels for many critical parts of your business.

When to Avoid Using Encapsulated O-Rings 

Of course, there are times in which encapsulated o-rings should be avoided. Firstly, they aren’t suitable for use under high pressure, as they are not designed for this application. Dynamic applications are also best avoided for safety reasons. When you are placing them in contact with abrasive media, you will find that encapsulated o-rings aren’t an effective solution. Finally, if your housing design needs excessive stretch, you’ll want to look for a solution that’s more flexible for your requirements.

Should You Use FEP or PFA? 

When choosing encapsulated o-rings, you’ll then have the choice between FEP and PFA. In general, you’ll find that PFA is best for use at high temperatures, as it is resistant to temperatures over 200°C. It offers all the same benefits as FEP, but it will also offer a longer service life. It has great mechanical and temperature resistance and is less likely to crack under stress or pressure. Of course, we recommend comparing prices as well, as this is often the biggest factor for companies. Delivery time is another consideration, as you may want to opt for the one that we have in stock at the time for any urgent projects.

Encapsulated o-rings offer a wide range of benefits to users, and you’ll find them to be a reliable solution for a wide range of applications.
