Where It Sits

This one measures 15.1 mm, 1.6 mm, NBR S7, and those figures are what separate it from the neighbouring numbers. Seal heads combine the oil seal, the dust seal and the bushing in one assembly. Öhlins uses seals with a spring-loaded lip so they follow the shaft as it wears. 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

The part number is the contract: it defines material, dimension and finish together. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. Service parts are ordered per piece unless stated otherwise. The exploded drawing for your unit names the number; if you do not have it, we do.

Identifying the Right Part

Part number 00338-05 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. inner diameter 15.1 mm, cross section 1.6 mm, material NBR S7 is what distinguishes this number from its neighbours in the range. Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position. A ring that has taken a set no longer springs back and starts to weep under 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.
