What It Is

Öhlins gives it as 46 mm, 2.5 mm, NBR 70; nothing about that is approximate. Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks. A ring that has taken a set no longer springs back and starts to weep under pressure. O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match.

Genuine Service Part

An original part keeps the unit within its published specification; a near-equivalent quietly moves it. The alternative to a service part is usually a new damper, which is why this catalogue exists. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. Service parts are ordered per piece unless stated otherwise.

How to Be Sure It Fits

Part number 00576-03 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Check inner diameter 46 mm, cross section 2.5 mm, material NBR 70 against what you have removed; a close size is not the same part. The groove does half the work: the ring only seals if the groove is clean and undamaged. An oil seal that has hardened lets the shaft pass oil past it, and the damping fades long before the leak becomes visible.

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.
