Where It Sits

The published figures are 31.47 mm, 1.78 mm, NBR 70. Measure the old part against them before ordering. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages. Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position. Seals are the part of a damper that decides whether it holds its gas charge and its oil, and they are the usual reason a unit ends up on the bench.

Original Öhlins Part

The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. If the unit is already apart, compare the published dimensions with the part in your hand. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.

How to Be Sure It Fits

Part number 00576-23 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. The published dimensions are inner diameter 31.47 mm, cross section 1.78 mm, material NBR 70 — measure the old part against them if you are unsure. Size is given as inner diameter and cross-section; a close size is not a match. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost.

Fitting and Setup Service

We are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.
