O-Rings

O-Rings are produced primarily from elastomer materials. O-Ring provides the sealing effect by deformation of the cross-section after assembly and by compressing it in the assembly area. O-Rings are mainly used for static sealing of gaseous and liquid media. Under certain conditions, dynamic use of an O-Ring is also possible.

Various materials are available such as NBR, FKM, EPDM, chloroprene, silicone, and fluoro silicon. Available for ISO 3601, AS 568, and other recognized standards. No matter you need metric or inch, standard or custom made O-Ring, all sizes of O-Rings are available.

This encapsulated O-Ring is produced from silicone or fluorocarbon with a seamless FEP jacket. These seals can solve sealing problems due to their chemical resistance coupled with elastic properties and low friction. Available to ISO 3601, AS 568 and BS 4518 and other standards including hollow and square sections. Available in both inch and metric sizes.

Polyurethane O-Rings are especially suited wherever O-Rings are subject to dynamic loads. This includes, for example, applications in hydraulics, pneumatics and in a wide range of other critical areas. In many cases, polyurethane O-Rings are used instead of NBR due to their high mechanical strengths.
