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.

Welche Branchen verwenden typischerweise metrische oder Zoll-Kits?
Each industry tends to follow regional manufacturing norms.
Industrie / Ausrüstung | Häufigster Kit-Typ | Warum? |
---|---|---|
Automobilindustrie (Europa) | Metrisches Kit | In der EU hergestellte Fahrzeuge entsprechen den ISO-Spezifikationen |
Automobilindustrie (USA/Japan) | Zoll-Kit | SAE-Standardgrößen dominieren |
Hydraulische Ausrüstung | Beide | Hängt von der Maschinenherkunft ab |
Industrielle Instandhaltung | Beide | Oft gemischte Flotten = beide Kits erforderlich |
OEM-Fertigung | Regionale Präferenz | Metrisch für EU, Zoll für US |
In sectors with global fleets, teams often choose beide Kits to prevent downtime.
Was passiert, wenn ich gemischte Maschinen verwende?
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.
