Assembly grease matters — the wrong compound swells the seal and it fails early. O-rings are single-use in a pressurised damper — they are replaced whenever the unit is opened. The dust seal does the hard work: it keeps the grit that would score the shaft away from the oil seal.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eSuspension is one of the few areas where the original part is genuinely the cheaper decision. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. We can supply the whole position from the drawing rather than the single piece if that is easier. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eOrder under 00438-60. Where several sizes share a description, only the number separates them. The published dimensions are inner diameter 49 mm, cross section 1.5 mm, material NBR 70 — measure the old part against them if you are unsure. Assembly grease matters — the wrong compound swells the seal and it fails early. Static seals and dynamic seals are not interchangeable even in the same size.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 00438-60\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 49 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 1.5 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":53648805855498,"sku":"00438-60","price":1.26,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-60_13dda2d6-301b-41d6-9553-fe3256a1d313.png?v=1788871967","url":"https:\/\/inter-pace.com\/products\/ohlins-o-ring-49x1-5-nbr-70-00438-60","provider":"Inter-Pace","version":"1.0","type":"link"}
