Measure the old part against them before ordering. 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. Seal kits gather the pieces one rebuild needs, which avoids a second order mid-job. A seal head combines the oil seal, the dust seal and the shaft bushing in one serviceable assembly.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. Öhlins parts are unit-specific: a close dimension is not a substitute. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eOrder under 00121-01. Where several sizes share a description, only the number separates them. The published dimensions are inner diameter 36 mm, outer diameter 12 mm — measure the old part against them if you are unsure. Öhlins builds the head so the dust seal takes the grit before it reaches the oil seal. Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\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 00121-01\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 36 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 12 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":53646841020682,"sku":"00121-01","price":55.98,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00121-01_164ec13b-c52a-4b56-b1ff-14dcf8941118.png?v=1788868634","url":"https:\/\/inter-pace.com\/products\/ohlins-seal-head-assy-36-12-00121-01","provider":"Inter-Pace","version":"1.0","type":"link"}
