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\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 00438-12\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eInner Diameter 19 mm\u003c\/li\u003e\n\u003cli\u003eMaterial NBR 70\u003c\/li\u003e\n\u003cli\u003eCross Section 2 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eThis one measures 19 mm, 2 mm, NBR 70, and those figures are what separate it from the neighbouring numbers. Öhlins specifies the compound by position: NBR where oil is the concern, FKM where heat is. The dust seal does the hard work: it keeps the grit that would score the shaft away from the oil seal. Seals harden with heat and age even when the machine has not been ridden much.\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. A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. If you are between two sizes, send us the measurement and we will check it against the catalogue. 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.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003ePart number 00438-12 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. The published dimensions are inner diameter 19 mm, cross section 2 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. Seals harden with heat and age even when the machine has not been ridden much.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eAsk us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.\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 00438-12\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 19 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 2 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":53648794419466,"sku":"00438-12","price":5000.0,"currency_code":"PYG","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-12_472aecaa-2b87-4392-b3b2-948c24878cfe.png?v=1788871911","url":"https:\/\/inter-pace.com\/en-py\/products\/ohlins-o-ring-19x2-nbr-70-00438-12","provider":"Inter-Pace","version":"1.0","type":"link"}
