Seals are the part of a damper that decides whether it holds its gas charge and its oil, and they are the usual reason a unit ends up on the bench.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThread M48x1.5\u003c\/li\u003e\n\u003cli\u003eOuter Diameter 20 mm\u003c\/li\u003e\n\u003cli\u003eInner Diameter 1.5 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 05615-01\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eAt 1.5 mm, 20 mm it fits one position only; the next size up carries a different number. The dust seal does the hard work: it keeps the grit that would score the shaft away from the oil seal. Assembly grease matters — the wrong compound swells the seal and it fails early. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. The alternative to a service part is usually a new damper, which is why this catalogue exists. The exploded drawing for your unit names the number; if you do not have it, we do. Where a number has been superseded, Öhlins states the replacement — we pass that on.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 05615-01 in the exploded view for the unit it belongs to. Check inner diameter 1.5 mm, outer diameter 20 mm against what you have removed; a close size is not the same part. Static seals and dynamic seals are not interchangeable even in the same size. A weeping damper almost always starts here.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 05615-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Seal Heads\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 1.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M48x1.5\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":53649967415562,"sku":"05615-01","price":446.0,"currency_code":"TTD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05615-01_8e44200b-c1d0-41c0-8017-f5a5264d756e.png?v=1788876899","url":"https:\/\/inter-pace.com\/en-tt\/products\/ohlins-seal-head-14-m48x1-5-20-05615-01","provider":"Inter-Pace","version":"1.0","type":"link"}
