An O-ring seals by being squeezed into its groove; the cross-section is therefore as important as the diameter. A leaking damper is not a cosmetic problem: it is a damper that has stopped controlling the wheel. O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. If you are between two sizes, send us the measurement and we will check it against the catalogue.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 00438-75. inner diameter 29 mm, cross section 5 mm, material FKM 70 is what distinguishes this number from its neighbours in the range. Assembly grease matters — the wrong compound swells the seal and it fails early. O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 00438-75\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 29 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eMaterial:\u003c\/em\u003e FKM 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":53646902624522,"sku":"00438-75","price":16.0,"currency_code":"BAM","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-75_f6120830-bca4-4982-a152-5ef8ae8007c2.png?v=1788869433","url":"https:\/\/inter-pace.com\/en-ba\/products\/ohlins-o-ring-29x5-fkm-70-00438-75","provider":"Inter-Pace","version":"1.0","type":"link"}
