Dimensions

JIS name: P-100

ID × CS: 99.6 × 5.7 mm

OD = ID + 2 × CS = 111.0 mm

Closest AS568 dimension

AS568-345

100.97 × 5.33 × 111.63 mm

This is a dimensional comparison only, not an interchangeability claim.

About tolerances

The public reference table notes that the listed dimensional tolerances are based on NBR. Different elastomer compounds may have different tolerances.

AS568 ↔ JIS comparison

Standard	ID (mm)	CS (mm)	OD (mm)
P-100	99.6	5.7	111.0
AS568-345	100.97	5.33	111.63

The AS568 result is the closest dimensional match in the current AS568 dataset. Similar dimensions do not establish interchangeability.
