Dust seals keep grit off the running surface; once they are torn, the oil seal behind them has a short life.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eMaterial NBR\u003c\/li\u003e\n\u003cli\u003eInner Diameter 17.8 mm\u003c\/li\u003e\n\u003cli\u003eCross Section 1.9 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 04722-36\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eThis one measures 17.8 mm, 1.9 mm, NBR, and those figures are what separate it from the neighbouring numbers. The dust seal does the hard work: it keeps the grit that would score the shaft away from the oil seal. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages. Static seals and dynamic seals are not interchangeable even in the same size.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eA damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins parts are unit-specific: a close dimension is not a substitute. Service parts are ordered per piece unless stated otherwise.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 04722-36. Öhlins states inner diameter 17.8 mm, cross section 1.9 mm, material NBR for this number, and those figures are the deciding ones. Seals harden with heat and age even when the machine has not been ridden much. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost.\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 04722-36\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 17.8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 1.9 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eMaterial:\u003c\/em\u003e NBR\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":53648959996170,"sku":"04722-36","price":4.45,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/04722-36_c03a6e10-42cf-4fda-ac8a-bdc9e4b554e6.png?v=1788872787","url":"https:\/\/inter-pace.com\/en-it\/products\/ohlins-o-ring-17-8x1-9-nbr-04722-36","provider":"Inter-Pace","version":"1.0","type":"link"}
