O-rings

O-rings

O-rings are circular seals with a circular cross section. O-rings can be produced in a wide range of materials and a series of compounds are available from stock as standard. The number of sizes of O-rings available is so large that almost any application can be realized.

O-rings are standardized in the DIN ISO 3601 (formerly DIN 3771). The simple form and reliability of the sealing function of O-rings is brilliant. The O-ring is the most widely used seal for this reason. The economical manufacture and uncomplicated assembly make the O-rings unsurpassed. The description of the O-rings consists of the dimensions of the inner diameter (d1) and the cord thickness (d2) in mm. with the material designation and its hardness (shore).

Special properties of O-rings

O-rings have a number of special properties. For example, O-rings offer high operating reliability and are suitable for small installation spaces. In addition, O-rings are easy to assemble, contribute to economic production and O-rings have high availability.

Applications for O-rings

O-ring seals are used in all sectors of industrial technology. In individual applications, a distinction is made between in static (no relative movement between the machine parts to be sealed) and dynamic (the machine parts to be sealed move relatively toward each other) applications. The vast majority of O-rings are used for sealing resting or slow-moving machine parts.
