Replacing seals at service intervals is far cheaper than replacing what a failed seal damages.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThickness 5 mm\u003c\/li\u003e\n\u003cli\u003eInner Diameter 18 mm\u003c\/li\u003e\n\u003cli\u003eOuter Diameter 30 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 04717-05\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eThis one measures 18 mm, 30 mm, 5 mm, and those figures are what separate it from the neighbouring numbers. Static seals and dynamic seals are not interchangeable even in the same size. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins keeps service parts available for units long after they leave the current price list. Suspension is one of the few areas where the original part is genuinely the cheaper decision. Where a number has been superseded, Öhlins states the replacement — we pass that on. The Öhlins exploded view names the number for each position; we can look it up if you do not have it.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eOrder under 04717-05. Where several sizes share a description, only the number separates them. inner diameter 18 mm, outer diameter 30 mm, thickness 5 mm is what distinguishes this number from its neighbours in the range. Dust seals keep grit off the running surface; once they are torn, the oil seal behind them has a short life. An oil seal that has hardened lets the shaft pass oil past it, and the damping fades long before the leak becomes visible.\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 04717-05\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Seals\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 18 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThickness:\u003c\/em\u003e 5 mm\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":53649394303242,"sku":"04717-05","price":20.23,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/04717-05_68550133-c2ce-4c28-b9df-3b703c8cb311.png?v=1788875248","url":"https:\/\/inter-pace.com\/products\/ohlins-seal-18-30-5-04717-05","provider":"Inter-Pace","version":"1.0","type":"link"}
