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.

¿Qué industrias suelen utilizar kits métricos o en pulgadas?
Each industry tends to follow regional manufacturing norms.
| Industria / Equipos | Tipo de kit más común | ¿Por qué? |
|---|---|---|
| Automoción (Europa) | Kit métrico | Los vehículos fabricados en la UE siguen las especificaciones ISO |
| Automotriz (EE. UU./Japón) | Kit de pulgadas | Los tamaños estándar SAE dominan |
| Equipo hidráulico | Ambos | Depende del origen de la máquina. |
| Mantenimiento industrial | Ambos | Flotas a menudo mixtas = se necesitan ambos kits |
| Fabricación OEM | Preferencia regional | Métrico para la UE, pulgadas para EE. UU. |
In sectors with global fleets, teams often choose ambos kits to prevent downtime.
¿Qué pasa si utilizo maquinaria mixta?
If you manage global equipment, you're not alone. One of our Middle Eastern clients uses both U.S. and German machines and keeps both kits on hand to ensure smooth repair workflows.
This dual-kit approach is common in logistics and industrial maintenance.
