What It Is

23.47 mm, 2.62 mm, FKM 70: that is the whole specification, and it has to match what came out. O-rings are single-use in a pressurised damper — they are replaced whenever the unit is opened. Seals harden with heat and age even when the machine has not been ridden much. O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match.

Original Öhlins Part

Rebuilding to specification only works if the parts are to specification — that starts here. Every part in this catalogue is one Öhlins fits itself during assembly and service. Order by part number — descriptions repeat across sizes, numbers do not. Tell us the damper's model designation and year and we will match the number for you.

How to Be Sure It Fits

Part number 00438-45 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. inner diameter 23.47 mm, cross section 2.62 mm, material FKM 70 is what distinguishes this number from its neighbours in the range. Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost.

Fitting and Setup Service

Fitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.
