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.
Feature | Metrisk O-ringsæt (428 STK) | Inch O-ringsæt (382 STK) |
---|---|---|
Målestandard | ISO / DIN (millimeter) | SAE / tomme (imperial) |
Antal størrelser | 30 | 30 |
Indre diameterområde | 3,00 – 48,50 mm | 2,90 – 43,82 mm |
Tværsnitsstørrelser | 1,50 / 2,00 / 2,50 / 3,00 mm | 1,78 / 2,62 / 3,53 / 5,33 mm |
Ideel til | EU/Asien maskiner, ISO udstyr | USA/Japan maskiner, SAE ventiler |
Case farve | Blå | Rød |
Vores O Ring sortimentssæt include both formats with labeled compartments and size charts.
Hvilke industrier bruger typisk metriske eller tommesæt?
Each industry tends to follow regional manufacturing norms.
Industri / Udstyr | Mest almindelige sættype | Hvorfor? |
---|---|---|
Automotive (Europa) | Metrisk sæt | EU-fremstillede køretøjer følger ISO-specifikationer |
Automotive (USA/Japan) | Inch sæt | SAE standardstørrelser dominerer |
Hydraulisk udstyr | Begge | Afhænger af maskinens oprindelse |
Industriel vedligeholdelse | Begge | Ofte blandede flåder = brug for begge sæt |
OEM-fremstilling | Regional præference | Metrisk for EU, Inch for USA |
In sectors with global fleets, teams often choose begge sæt to prevent downtime.
Hvad hvis jeg bruger blandede maskiner?
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.
