Product Description
O-rings are circular sealing elements with circular cross-sections, may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. O-ring selection is based on chemical compatibility, application temperature, sealing pressure, lubrication requirements, durometer, size and cost. We offer you a range of elastomeric materials for both standard and special applications which allow the O-Ring to seal practically all liquid and gaseous media.
