The dust seal does the hard work: it keeps the grit that would score the shaft away from the oil seal.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMaterial NBR 70\u003c\/li\u003e\n\u003cli\u003eCross Section 2.4 mm\u003c\/li\u003e\n\u003cli\u003eInner Diameter 44.6 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00438-68\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eThis one measures 44.6 mm, 2.4 mm, NBR 70, and those figures are what separate it from the neighbouring numbers. Öhlins specifies the compound by position: NBR where oil is the concern, FKM where heat is. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThe part is identical to what Öhlins fits in production — same supplier, same specification. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Service parts are supplied per piece unless the description says otherwise. We can check the number against the Öhlins exploded view before you order — just ask.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003ePart number 00438-68 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins states inner diameter 44.6 mm, cross section 2.4 mm, material NBR 70 for this number, and those figures are the deciding ones. Öhlins specifies the compound by position: NBR where oil is the concern, FKM where heat is. An oil seal that has hardened lets the shaft pass oil past it, and the damping fades long before the leak becomes visible.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre.
