Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure. A leaking damper is not a cosmetic problem: it is a damper that has stopped controlling the wheel. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Suspension is one of the few areas where the original part is genuinely the cheaper decision. 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\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003ePart number 05053-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. The published dimensions are inner diameter 21.82 mm, cross section 3.53 mm — measure the old part against them if you are unsure. Seals harden with heat and age even when the machine has not been ridden much. Assembly grease matters — the wrong compound swells the seal and it fails early.\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 05053-01\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 21.82 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 3.53 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":53649712546058,"sku":"05053-01","price":5.36,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05053-01_5824af40-d3a4-4f8d-bc17-6f652f7fcf0c.png?v=1788876279","url":"https:\/\/inter-pace.com\/products\/ohlins-x-ring-21-82x3-53-05053-01","provider":"Inter-Pace","version":"1.0","type":"link"}
