O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 00638-08\u003c\/li\u003e\n\u003cli\u003eInner Diameter 59.92 mm\u003c\/li\u003e\n\u003cli\u003eCross Section 3.53 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eMaterial NBR 70\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eDimensionally this is 59.92 mm, 3.53 mm, NBR 70, which is how it is told apart from the rest of the range. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure. The dust seal does the hard work: it keeps the grit that would score the shaft away from the oil seal. Öhlins uses seals with a spring-loaded lip so they follow the shaft as it wears.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins keeps service parts available for units long after they leave the current price list. A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. Tell us the damper's model designation and year and we will match the number for you. Order by part number. The dimensions below are the ones Öhlins publishes for it.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 00638-08 in this case. Check inner diameter 59.92 mm, cross section 3.53 mm, material NBR 70 against what you have removed; a close size is not the same part. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure.\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 00638-08\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 59.92 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 3.53 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":53648915628298,"sku":"00638-08","price":200.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00638-08_b185258d-947f-4be9-b556-14dc2b5b5866.png?v=1788872597","url":"https:\/\/inter-pace.com\/en-in\/products\/ohlins-o-ring-59-92x3-53-00638-08","provider":"Inter-Pace","version":"1.0","type":"link"}
