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\u003eInner Diameter 35.1 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eMaterial NBR 70\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00438-18\u003c\/li\u003e\n\u003cli\u003eCross Section 1.6 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eÖhlins publishes 35.1 mm, 1.6 mm, NBR 70 for 00438-18 — the dimensions are the identity of the part. Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks. O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match. Static seals and dynamic seals are not interchangeable even in the same size.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Tell us the damper's model designation and year and we will match the number for you. Where a number has been superseded, Öhlins states the replacement — we pass that on.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e00438-18 is the Öhlins number for this position — the same one printed in the service documentation. Check inner diameter 35.1 mm, cross section 1.6 mm, material NBR 70 against what you have removed; a close size is not the same part. Seal heads combine the oil seal, the dust seal and the bushing in one assembly. Seals harden with heat and age even when the machine has not been ridden much.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBrand:\u003c\/em\u003e Öhlins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart Number:\u003c\/em\u003e 00438-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e O-Rings\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 35.1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 1.6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eMaterial:\u003c\/em\u003e NBR 70\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCountry of Origin:\u003c\/em\u003e Sweden\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53646899478794,"sku":"00438-18","price":6.0,"currency_code":"TTD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-18_82269fc3-2692-4502-8a11-ee3ae166545d.png?v=1788869379","url":"https:\/\/inter-pace.com\/en-tt\/products\/ohlins-o-ring-35-1x1-6-nbr-70-00438-18","provider":"Inter-Pace","version":"1.0","type":"link"}
