O-Rings O-rings are circular sealing elements with circular cross-sections, and are mainly used in static applications. The sizes are specified by the inside diameter and the cross section diameter. Our O-rings are manufactured according to metric and imperial international standards such as AS 568B, DIN ISO 3601 and JIS.
The proper o-ring size is a fundamental aspect of proper o-ring performance. Whether your application conforms to U.S., Japanese JIS, British BS, or Common Metric sizing for o-rings, these o-ring size charts will help you locate the right o-ring size.
Selecting the appropriate fluoroelastomer ultimately will be determined on the desired: Resistance to amines or caustics Resistance to hydrocarbon fluids Flexibility at low temperature (ability to maintain a seal at low temperature) See the chart below for general performances differences.
