1. What Are Rubber O Rings?

Rubber O rings are the particular type of seal rings made up of the highest quality silicone. They are also called the mechanical gaskets for the gas cylinders having a specified cross-section.

Rubber o-rings are also considered packing joints that act as a stable loop for sealing the different applications.

In addition to this, these unique silicone O rings are mainly designed to be installed in the grooves or between the compressed parts of two different parts.

In such a way, the rubber O rings will create a seal for the package at the interface. These rings are mainly used in the parts where there are relatively static or dynamic motions.

They are also made up of the highest vulcanized solid material, which makes them resistant to other fluids, gases, and unfavorable environmental conditions.

  • Viton O rings

All these O rings are distinguished by the different types of materials used in their construction. Other than this, they perform the same function to seal the containers.

7. How Are Rubber O-Rings Sized?

The sizing of the rubber O rings depends on the three dimensions regarding the application you’re using.

You need to keep in mind these three dimensions while sizing the rubber O rings include the Outside Diameter (OD), the Inside Diameter (ID), and the most important one is the Cross Section.

The manufacturers are suggested to compare these dimensions very carefully when sizing all types of rubber O-rings.

The sizing of the rubber O-rings is considered a pretty simple procedure. The engineers are advised to record all measurements of the O-rings in millimeters.

8. What Is The Difference Between Black O Rings And Green O Rings?

The primary difference between the black O-rings and green O-rings is the nature of the materials used in their construction.

Black O-rings are mainly made up of the highest quality of the Neoprene or Nitrile material. In some cases, there is a combination of two different materials.

Whereas the green-colored O-rings are made up of the premium quality of Hydrogenated Nitrile, also known as saturated nitrile or HNBR.

Besides the nature of the materials, the green and black O-rings also differ in their applications.

Black O-rings are mainly used for auto-air conditioning applications, whereas green O-rings deal with the high-temperature values and the intense working stress. They are integrated into the solar systems.

9. How Do I Know What Size O-Ring To Buy?

You can know the correct size of the O-ring according to the desired application.

The majority of the potential manufacturers in China offer various sizes of rubber O-rings for different applications.

Thus, you must have an idea about the insights of the application before choosing the right size of the rubber O-ring.

10. How Do You Select an O-Ring Cross-Section?

You can select the proper O-ring cross-section by following the given steps:

  • You can take an estimate of the O-ring cross-section by taking an idea from the available sizes.
  • The next step for selecting the right O-ring cross-section is to check the maximum clearance of your application.
  • Check the radial seal of the application.
  • Make sure that the calculated clearance must be acceptable for the application pressures.
  • Now when you’re done with calculating the clearance of the application, the next step is to calculate the O-ring groove dimensions.
  • Check the gland depth of the application for the Or-rings
  • Don’t forget to check the groove width. It must be larger than the thickness of the backup ring
  • Also, determine the maximum perfect gland fill of the application
  • Also, calculate the seal squeeze for deciding the right O-ring cross-section

11. Is Rubber O-Rings Fuel/Oil Resistant?

Yes, almost all types of rubber O-rings are considered fuel/oil resistant. This is why they are used in a wide variety of applications.

The different rubber O-rings are resistant to many substances, including water, fuel, oil, gasoline, petroleum oils, crude oil, and even propane.

The resistance property of the rubber O-ring has made them perfect for a wide variety of applications under different temperature conditions.

Rubber O-Rings Fuel and Oil Resistant

12. Do The Color Of O-Rings Make A Difference?

Yes, the color of an O-ring makes a significant difference in its properties and applications.

The color of the O-rings comes from the material or combination of materials used in their construction.

That is why manufacturers like BAIWE provide an extended list of the O-rings depending on their length.

Furthermore, the O-ring color affects the material’s compression and the property of the O-ring, including the resistance and physical properties.

Do O-Rings Come In Different Thicknesses?

Yes, O-rings are available in different thicknesses depending on the type of applications they offer.

The thickness of the o-rings differs both in inches and millimeters. The cross-sectional area of the O-rings is directly related to their thickness.

The estimated Diameter of the rubber O-rings ranges from 0.040 to 0.275 inches. However, the insider diameter of these O-rings ranges from 0.029 to 25.940 inches.

13. Is Silicone O-Rings Better Than Rubber?

Yes, silicone O-rings are better than rubber O-rings because they can easily be applied to high temperatures without getting any substantial change in their properties.

In addition to this, the silicone O-rings aren’t affected by the other elements, thereby causing no problem in their applications.

Silicone O-rings give a better range of benefits, including high thermal stability and substantial chemical resistance.

14. Do Rubber O-Rings Stretch?

Yes, rubber O-rings can easily be stretched but only to a particular extent. By stretching them, you can fit them snugly in the groove of the applications.

However, the stretch in the rubber O-ring is estimated up to 1% to 5%, with mostly 2% in the majority of the applications.

The stress significantly accelerates the cross-section reduction and aging of the rubber O-rings due to stretch.

15. Can You Use Rubber Instead Of an O Ring?

Yes, you can use rubber instead of O-ring since it’s regarded as the best substitute for all types of seals.

The majority of the manufacturers prefer using the rubber seal gaskets instead of the O-rings in various applications.

Furthermore, there are also many other options that you can use as the best alternative for O-rings. These substitutes include flange seals, static radial seals, composite sealing plates, axial face seals, and press-in place seals.

 Silicone O-Rings Better Than Rubber

16. Does Rubber Oil Swell O-Rings?

Yes, rubber oil causes the O-rings to swell. However, the amount of swelling in O-rings depends directly on the chemistry of the oil and the exposure temperature.

The greater the exposure temperature, the greater the swelling in the O-rings.

Besides this, the majority of the manufacturers in China have now developed elastomers that reduce the swelling extent in the O-rings when exposed to rubbers.

Other than this, the swelling of the O-ring will continue to rise unless the insider elastomer maintains a stable equilibrium.

17. How Much Should An O-Ring Be Compressed?

An O-ring can be compressed up to 1% to 5% depending on the pressure and the temperature applied.

The compression of an O-ring also depends on its inside Diameter. For compressing the O-ring to a substantial value, it’s suggested to have a smaller piston groove diameter.

Compression larger than 5% in the O-rings is not recommended.

 Compressing of O-ring

18. How Do You Make O-Rings Seal Better?

You can make the O-ring seals better by following the given tips:

  • Make sure to consider the environmental conditions, including the temperature, when selecting the elastomers
  • Check the appropriate dimensions of the O-rings seal for their better working
  • The size of the O-rings seal must be equal to the application’s size
  • Calculate the volume/void ratio before installing the O-rings seals on the applications
  • Test the working of O-ring seals before using them
  • Consider the application type for making the O-ring seal perform in a better way

19. How And Why Do You Lubricate Rubber O-Rings?

You can use the highest quality of silicone oil or molybdenum disulfide for lubricating the rubber O-rings. The lubrication of the rubber O-rings must be carried out before or after molding while treating the seal.

In addition to this, the lubrication of the rubber O-rings must be carried out on the surface of the molded rubber products.

You should lubricate the rubber O-rings because:

  • It helps to increase the lifespan of the O-rings
  • It protects the O-rings from pinching and cutting
  • The cracking is also reduced because of lubrication in the rubber O-rings
  • The installation is also carried out quickly with the lubrication of O-rings

20. Do O Rings Stretch Over Time?

Yes, the majority of the O-rings become stretched or loose over time and need to be replaced or removed for the better working of the applications.

The properties of the rubber O-rings make them change their size over time, thereby leading to increased expansion.

Moreover, the O-rings also stretch over time when they are exposed to high temperatures.

21. What Are FFKM O Rings?

The FFKM O-rings are precisely described as Perflouroelastomer seals. Unlike the rubber O-rings, they are considered the best innovation.

The primary reason behind the increasing demand of the FFKM O-rings is their sufficient resistance towards chemicals and high temperatures.

Moreover, they are also resistant to the degradation caused by aggressive fluids and gases.
