O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match. Seal kits gather the pieces one rebuild needs, which avoids a second order mid-job. Size is given as inner diameter and cross-section; a close size is not a match.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. 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. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003ePart number 00338-70 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Check inner diameter 27 mm, cross section 4 mm, material NBR 70 against what you have removed; a close size is not the same part. An O-ring seals by being squeezed into its groove; the cross-section is therefore as important as the diameter. Öhlins specifies the compound by position: NBR where oil is the concern, FKM where heat is.\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 00338-70\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 27 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 4 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":53646887158026,"sku":"00338-70","price":7.27,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00338-70_71d042c7-f8ab-49b9-b472-b5d2cdfbc8b4.png?v=1788869203","url":"https:\/\/inter-pace.com\/en-es\/products\/ohlins-o-ring-27x4-nbr70-00338-70","provider":"Inter-Pace","version":"1.0","type":"link"}
