O-Rings and Related Products

An O-Ring is a simple circular sealing ring with a round cross section, a torus, usually made from an elastomeric material. The O-Ring's simple design lends itself to a multitude of sealing uses, including static and reciprocal dynamic applications at low speed and low pressure in addition to rotary and oscillating applications.
