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.

Ce industrii folosesc de obicei kituri metrice sau inci?
Each industry tends to follow regional manufacturing norms.
| Industrie / Echipamente | Cel mai comun tip de kit | De ce? |
|---|---|---|
| Automobile (Europa) | Kit metric | Vehiculele fabricate în UE respectă specificațiile ISO |
| Automobile (SUA/Japonia) | Kit inch | Dimensiunile standard SAE domină |
| Echipamente hidraulice | ambele | Depinde de originea mașinii |
| Întreținere industrială | ambele | Adesea flote mixte = au nevoie de ambele kituri |
| Producție OEM | Preferință regională | Metric pentru UE, inch pentru SUA |
In sectors with global fleets, teams often choose ambele truse to prevent downtime.
Ce se întâmplă dacă folosesc utilaje mixte?
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.
