The O-ring is a simple circular torus, usually made of an elastomeric material. This simple design leads to its use in a wide variety of applications—static, reciprocal, oscillating, and dynamic applications—at low speed and pressure. It is the most commonly used sealing solution. In higher pressure conditions, a backup ring greatly increases the extrusion resistance of the O-ring.
We have O-rings in diverse sizes and materials. We also have more advanced sealing designs such as X-rings, which are specially designed for low pressure sealing.
