A leaking damper is not a cosmetic problem: it is a damper that has stopped controlling the wheel. Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position. Seal kits gather the pieces one rebuild needs, which avoids a second order mid-job.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThis is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. For a full rebuild, the seal kit plus the wear parts is usually the sensible order. Öhlins parts are unit-specific: a close dimension is not a substitute.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003e00438-10 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states inner diameter 52 mm, cross section 3 mm, material NBR 70 for this number, and those figures are the deciding ones. 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\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 00438-10\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 52 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 3 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":53646899249418,"sku":"00438-10","price":17.23,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-10_c366579d-61dc-4609-9427-3d9b9776b2e0.png?v=1788869374","url":"https:\/\/inter-pace.com\/en-fo\/products\/ohlins-o-ring-52x3-nbr-70-00438-10","provider":"Inter-Pace","version":"1.0","type":"link"}
