What It Is

Dimensionally this is 4 mm, 1 mm, NBR 70, which is how it is told apart from the rest of the range. 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. Size is given as inner diameter and cross-section; a close size is not a match. Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position.

Genuine Service Part

Öhlins keeps service parts available for units long after they leave the current price list. Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. The exploded drawing for your unit names the number; if you do not have it, we do. The Öhlins exploded view names the number for each position; we can look it up if you do not have it.

Identifying the Right Part

Part number 00638-13 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins states inner diameter 4 mm, cross section 1 mm, material NBR 70 for this number, and those figures are the deciding ones. Assembly grease matters — the wrong compound swells the seal and it fails early. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure.

Fitting and Setup Service

If you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.
