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.
| Caratteristica | Kit O-ring metrico (428 pezzi) | Kit O-ring da pollici (382 pezzi) |
|---|---|---|
| Standard di misurazione | ISO / DIN (millimetri) | SAE / Pollici (imperiali) |
| Numero di dimensioni | 30 | 30 |
| Gamma di diametri interni | 3,00 – 48,50 millimetri | 2,90 – 43,82 millimetri |
| Dimensioni della sezione trasversale | 1,50 / 2,00 / 2,50 / 3,00 millimetri | 1,78 / 2,62 / 3,53 / 5,33 millimetri |
| Ideale per | Macchinari UE/Asia, attrezzature ISO | Macchine USA/Giappone, valvole SAE |
| Colore della cassa | Blu | Rosso |
Nostro Kit assortimento O-ring include both formats with labeled compartments and size charts.
In quali settori vengono solitamente utilizzati kit con misure metriche o in pollici?
Each industry tends to follow regional manufacturing norms.
| Industria / Attrezzature | Tipo di kit più comune | Perché? |
|---|---|---|
| Automobilistico (Europa) | Kit metrico | I veicoli fabbricati nell'UE seguono le specifiche ISO |
| Automotive (USA/Giappone) | Kit pollici | Le dimensioni standard SAE sono dominanti |
| Attrezzatura idraulica | Entrambi | Dipende dall'origine della macchina |
| Manutenzione industriale | Entrambi | Spesso flotte miste = servono entrambi i kit |
| Produzione OEM | Preferenza regionale | Metrico per UE, pollici per USA |
In sectors with global fleets, teams often choose entrambi i kit to prevent downtime.
Cosa succede se utilizzo macchinari misti?
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.
