Applications:

An O-ring is a type of round or donut-shaped seal and is most commonly used to stop fluids or air passing through into another area. O-rings are normally seated between two sections and when compressed, they form a secure seal that prevents particle, vapour and fluid leakage which in turn protects and maintains pressure whilst keeping debris out, ensuring proper function and safety. They come in different sizes and materials, depending on the application they are used for, so it is important to consider what materials and fluids are going to be in contact with the seal to ensure it is the right one. These seals or gaskets are most commonly used in:

Industrial and manufacturing applications

Plumbing

Hydraulics and pneumatics

Automotive manufacturing and repair

Power transmission technology

How long does an O-Ring last for?

If the O-ring is used in the correct conditions for the material, FKM O-rings can last indefinitely
