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.

| Ideal para | Máquinas UE/Ásia, equipamentos ISO | Máquinas EUA/Japão, válvulas SAE |
| Cor da caixa | Azul | Vermelho |
Nosso Kits de sortimento de anéis O include both formats with labeled compartments and size charts.
Quais indústrias normalmente usam kits métricos ou em polegadas?
Each industry tends to follow regional manufacturing norms.
| Indústria / Equipamentos | Tipo de kit mais comum | Por que? |
|---|---|---|
| Automotivo (Europa) | Kit Métrico | Veículos fabricados na UE seguem especificações ISO |
| Automotivo (EUA/Japão) | Kit de Polegadas | Os tamanhos padrão SAE dominam |
| Equipamentos Hidráulicos | Ambos | Depende da origem da máquina |
| Manutenção Industrial | Ambos | Frotas frequentemente mistas = precisam de ambos os kits |
| Fabricação OEM | Preferência regional | Métrica para UE, polegada para EUA |
In sectors with global fleets, teams often choose ambos os kits to prevent downtime.
E se eu usar maquinário misto?
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.
