Replacing seals at service intervals is far cheaper than replacing what a failed seal damages. Replacing the head as a unit is usually faster and more reliable than fitting the seals individually. Öhlins builds the head so the dust seal takes the grit before it reaches the oil seal.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eA damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. Every part in this catalogue is one Öhlins fits itself during assembly and service. For a full rebuild, the seal kit plus the wear parts is usually the sensible order. Order by part number. The dimensions below are the ones Öhlins publishes for it.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21025-01. Check inner diameter 14 mm, outer diameter 36 mm against what you have removed; a close size is not the same part. Dust seals keep grit off the running surface; once they are torn, the oil seal behind them has a short life. 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 21025-01\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 14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 36 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":53652478198026,"sku":"21025-01","price":68.8,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21025-01_a6cfb163-5d67-4ca4-9577-8ec232b7d6b4.png?v=1788879337","url":"https:\/\/inter-pace.com\/products\/ohlins-seal-head-assy-14-36-21025-01","provider":"Inter-Pace","version":"1.0","type":"link"}
