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\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eOuter Diameter 30 mm\u003c\/li\u003e\n\u003cli\u003eInner Diameter 47.3 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 15551-04\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eThe published figures are 47.3 mm, 30 mm. Measure the old part against them before ordering. Seal heads combine the oil seal, the dust seal and the bushing in one assembly. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost. Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe part is identical to what Öhlins fits in production — same supplier, same specification. An original part keeps the unit within its published specification; a near-equivalent quietly moves it. Tell us the damper's model designation and year and we will match the number for you. The exploded drawing for your unit names the number; if you do not have it, we do.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e15551-04 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states inner diameter 47.3 mm, outer diameter 30 mm for this number, and those figures are the deciding ones. Öhlins uses seals with a spring-loaded lip so they follow the shaft as it wears. 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\u003eAsk us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.\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 15551-04\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Sealing Washers\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 47.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 30 mm\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":53652413088010,"sku":"15551-04","price":16.36,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15551-04_c9df07a1-bf29-47c3-ae25-7f191da5d078.png?v=1788879057","url":"https:\/\/inter-pace.com\/en-fi\/products\/ohlins-seal-washer-47-3-30-15551-04","provider":"Inter-Pace","version":"1.0","type":"link"}
