Replacing seals at service intervals is far cheaper than replacing what a failed seal damages. O-rings are single-use in a pressurised damper — they are replaced whenever the unit is opened. 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\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe part is identical to what Öhlins fits in production — same supplier, same specification. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e00438-59 is the Öhlins number for this position — the same one printed in the service documentation. The published dimensions are inner diameter 37 mm, cross section 3 mm, material NBR 70 — measure the old part against them if you are unsure. O-rings are single-use in a pressurised damper — they are replaced whenever the unit is opened. A ring that has taken a set no longer springs back and starts to weep under pressure.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eWe are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.\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 00438-59\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 37 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":53646902133002,"sku":"00438-59","price":11.74,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-59_a94c1b62-8a81-411d-bc72-00bbf7934594.png?v=1788869423","url":"https:\/\/inter-pace.com\/en-dk\/products\/ohlins-o-ring-37x3-nbr-70-00438-59","provider":"Inter-Pace","version":"1.0","type":"link"}
