Dimensions
| Dimension | Inches | Millimetres |
|---|---|---|
| Inside diameter (ID) | 0.362″ | 9.19 mm |
| Cross section (CS) | 0.103″ | 2.62 mm |
| Outside diameter (OD) | 0.568″ | 14.43 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 9.19 mm, because compression set is permanent. If your measurement came in a little under this and the cross section roughly matches, -110 is very likely still the correct part. Ordering the size your worn ring measures is how the same failure repeats. More on this →

These share the same 3/32" cross section, so if the thickness is right but the diameter is off, your ring is probably one of these.
