O-Rings are a widely used seal in industry because they are inexpensive, effective and versatile. They are suitable for both static and dynamic applications. The seal is made from a variety of elastomer materials suitable for different environments and temperatures, and it is important to choose the O-Ring made with a material that is appropriate for the purpose.
What are O-Rings used for? O-Rings are used to seal a joining of two pieces to ensure that no gas or liquid can pass. The O-Ring is fitted into a groove and designed to resist pressure. The resistance prevents gas or liquid from escaping or entering the joining. Whenever two pieces of a machine are connected, there is a risk that gas or liquid substance could leak through the area where the two edges meet. Where the two pieces connecting are round, such as piping, an O-ring can be a cost effective solution. An O-Ring can seal the joint to ensure that no gas or fluid can enter or escape. As joints can be the weakest spot in a piece of machinery, a high quality O-Ring made from the correct substance can protect and ensure longevity of your machinery and applications.
It is important to understand the material an O-Ring is made of. At Kemtron we can supply special sizes which can be manufactured (cord and vulcanised joint) from a variety of materials such as Nitrile (NBR), Viton, EPDM, Silicone, PTFE, Chemraz, Neoprene and Fluorinated Ethylene Propylene (FEP) encapsulated (SIlicone/Viton). We hold an extensive selection of O’Rings at our factory for immediate dispatch.
O-Rings do not last forever and we recommend that you hold some spares in stock. At Kemtron we can also supply you with your own instant O-Ring making kit to deal with emergency leaks which you can use while you wait for any replacement stock.
