O-Rings and Related Products

The O-ring is the most common type of fluid seal.  An O-ring's simple design lends itself to a multitude of sealing uses, including static, reciprocal, oscillating, and dynamic applications at low speed and pressure.  In elevated operating pressure environments, addition of a backup ring will greatly increase the extrusion resistance of an O-ring. 

The most basic shape of an O-ring is a simple circular sealing torus, usually made from an elastomeric material. Beyond the standard O-ring, RT/Dygert can supply more advanced sealing designs such as Quattro Seals, which are specially designed for low pressure sealing.  RT/Dygert also offers O-rings in advanced materials such as Viton®, Viton Extreme®, and Teflon®.

RT/Dygert stocks over 200 million O-rings in 13,000 different size and material combinations.
