Confused by metric vs inch O ring kits? You’re not alone. With machinery sourced globally, choosing the wrong standard can cause costly sealing errors.

Choose the right sizing system to match your equipment origin and avoid downtime.

Read on to learn how to pick the right kit—and why many technicians stock both for maximum flexibility.

What’s the difference between metric and inch O ring kits?

Metric kits follow ISO/DIN sizing in millimeters. Inch kits follow SAE standards using imperial measurements.

If your equipment is built in the U.S. or Japan, inch kits are likely correct. For EU and many Asian machines, metric is the way to go.

Náš Sady sortimentu O kroužků include both formats with labeled compartments and size charts.

Která průmyslová odvětví obvykle používají metrické nebo palcové sady?
