2.364″ × 0.07″ ·
outside diameter 63.6 mm (2.504″)
Dimensions
| Dimension | Inches | Millimetres |
|---|---|---|
| Inside diameter (ID) | 2.364″ | 60.05 mm |
| Cross section (CS) | 0.07″ | 1.78 mm |
| Outside diameter (OD) | 2.504″ | 63.6 mm |
Outside diameter is not measured, it is derived: OD = ID + 2 × CS.
If your measured OD disagrees with this, trust the ID and cross section — measuring
across the outside of a flexible ring is the least reliable of the three.
If you measured a used one
A ring pulled out of service will measure smaller than 60.05 mm, because compression set is permanent. If your measurement came in a little under this and the cross section roughly matches, -036 is very likely still the correct part. Ordering the size your worn ring measures is how the same failure repeats. More on this →
Nearby sizes in the 000 series
These share the same 1/16" cross section, so if the thickness is right but the diameter is off, your ring is probably one of these.
