A Complete Guide – What Is Rubber Silicone O-Rings?

A O-rings is a mechanical gasket which has industrial uses. It is in the shape of a torus. According to geometry, a torus is a surface of revolution generated by revolving a circle in three-dimensional space about an axis that is coplanar with the circle. Chemically, these rubber silicone O-rings consists of methyl and vinyl groups, attached to the main silicone chain. One of the greatest traits of rubber silicon O-rings is its ability to withstand extreme and harsh temperatures and thermal cycling. Thermal cycling is a process that involves exposing and passing through a substance through two extreme temperatures. It is an environmental stress test used to evaluate product reliability. This process also helps to capture or recognise manufacturing defects. Thus, thermal cycling helps in early diagnosis of any sort of defect present in the considered product.

The O-rings is generally used in static and dynamic applications. These silicone rings are used in places where there is relative motion between the parts and the O ring. Due to its heat withstanding capacity, it is used in places where friction occurs or at least has a tendency to occur. Some of the dynamic applications where this rubber silicone ring is used are- rotating pump shafts and hydraulic cylinder pistons.  Some of the static applications where this ring is used are- gas and fluid sealing.

Rubber silicone O-rings are generally used as seals and are the most preferred seals due to its several advantages. Some of its commonly known advantages are- inexpensive, easy to manufacture, are very reliable and has very simple techniques of mounting, thus, it is not very complex to use. The procedures are quite simple to understand and perform.

Varieties Of O-Rings

Rubber silicone O-rings are available in varieties. They have a variety of and are available in different shapes and sizes. Sizes of the rings are signified and the inside and outside diameter. Different applications need different rings that will provide utmost satisfaction to the specific requirement. Thus, the ring that suits the application best or that is providing the utmost advantage to the considered application should be chosen.

Advantage Of Rubber Silicone O Ring

There are several advantages and traits of rubber silicone O-rings. Some are given down below-

  • These silicone rings are remarkably versatile.
  • The rubber in these rings enables it to be immensely flexible.
  • One of the many traits of these rubber silicone rings is their ability to withstand extreme heat. Its quality of heat resistance is applaudable.
  • These silicone rings also have a shore of hardness.
  • It can easily work and function effectively in cold temperatures up to -50 degree
  • These rings can be used in places where damage is a factor.
  • These rings are also resistant to ozone, ultraviolet rays, and many other oils.
  • Rubber silicone rings also offer low compression set characteristics.
  • These rubber silicone rings can also be modified into having flame retardant.
  • These rings can also be modified into electrically resistant or can be changed and transformed into being a conductor.
  • These rubber rings are extremely cost-efficient.

Types Of Rubber Silicone O-Rings

There are obviously a vast range of rings to choose from. However, the following important ones are discussed below-

  • FDA Silicone O-rings
  • Vulcanized Silicone O-rings
  • Rubber Silicone O-rings
  • Custom Silicone Rubber O-rings
  • Mate Datatable Silicone O-rings

These types of rings shall be discussed further:

1.) FDA Silicone O-Rings:

As commonly misunderstood FDA does not certify or approve O-rings. O-rings are such items that are even used in the food industry. Both food and pharmaceutical companies use this. They publish and specify guidelines that list the ingredients that are safe to be used in applications where the rubber rings will come in contact with food or food materials. After getting the specified materials, it is the duty of the manufacturer to follow the given instructions and abide by it.

2.) Vulcanized Silicone O-Rings:

Vulcanized O-rings are made from extruded cord stock that has been cut and bonded together. This process is the opposite of the process that is done to manufacture molded O-rings. These silicone O-rings are generally used in static applications where molded O-rings cannot be brought to use due to non-standard dimensions, where only small pieces are required. Vulcanized silicone O-rings can be made from a vast range of elastomers and literally can be made in almost any size.

3.) Rubber Silicone O-Rings:

Rubber silicone O-rings are elastomer products that have a vast range of uses. This means that this type of O-rings is used widely used in multiple types of applications. Another major advantage of these types of rings is their property of being cost-efficient. These types of rings are very inexpensive and thus are very affordable. These provide very easy and fast sealing methods. Using them is not very difficult or complicated. They are very easy to mount and do not involve any complicated technique. These rings can seal properly and avoid leakage from anywhere at all.

4.) Custom Silicone Rubber O-Rings:

There has been a steep and constant growth in the demand for custom silicone rubber O-rings. The main reason for this increasing demand is that this ring can be modified and changed to suit the exact requirement and satisfy the exact demand without having to compromise or adjust. A range of elements and plastic compounds are used to manufacture this type of rubber ring. This rubber ring can be specifically customized to satisfy the desired requirement. Thus, it makes it easier for it to be used.

5.) Hollow O-Rings

This is basically an alternative for standard O-rings. Therefore, this is an alternative product that may or can be used in the place of the standard rings. These hollow O-rings can only be used in places where low closing force is required. It is suitable for applications having a rough uneven surface and in low-pressure static applications. However, these rings are not suitable in places where high pressure is involved and in dynamic applications.

Thus, silicone rings are cheap yet very efficient. They satisfy their function very decently. They are very easy to use and therefore, do not make the process of mounting them very difficult. This makes these rubber silicone O-rings very easy to use. Their property to withstand extreme temperature and is very cost-efficient is what makes them preferable.

The accessibility of rubber silicone rings is another advantage that definitely draws a lot of positive attention towards it. They are easily available in cities and can easily be accessed. Thus, its easiness is something that should obviously be considered and deemed important. Getting one’s hands on it is no complex method. Therefore, these rings satisfy many requirements without having any complications.
