O-ring

A universal applicable sealing element, used mainly for static sealing. Tolerance and surface are according to the DIN ISO 3601.
An O-ring is an endless round ring that has a circular cross-section. It is extremely efficient and acts as a sealing element for static and subordinate dynamic applications. The sealing effect comes into play during installation due to the axial or radial compression of the cross section.
O-rings are available in a variety of different elastomer materials. The most common are NBR, HNBR, FKM, EPDM, CR and VMQ.
We would be pleased to offer you various O-ring assortment boxes upon request.
