An O-ring is a loop of elastomer with a round (o-shaped) cross-section used as a mechanical seal or gasket. They are designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.

The joint may be static, or (in some designs) have relative motion between the parts and the o-ring; rotating pump shafts and hydraulic cylinders, for example. Joints with motion usually require lubrication of the o-ring to reduce wear. This is typically accomplished with the fluid being sealed.

At Sentosa, we carry O-ring of various sizes and dimensions with properties such as ability to withstand high temperature, high pressure and resistant to chemical.

We have O-rings made from the following materials:

  • NBR
  • EPDM
