O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match. Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position. Seal kits gather the pieces one rebuild needs, which avoids a second order mid-job.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins publishes dimensions for its service parts so a workshop can verify before it fits. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. The exploded drawing for your unit names the number; if you do not have it, we do.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eOrder under 04722-49. Where several sizes share a description, only the number separates them. Öhlins states inner diameter 31.2 mm, cross section 2.4 mm, material NBR for this number, and those figures are the deciding ones. O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure.\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 04722-49\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 31.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 2.4 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":53648960946442,"sku":"04722-49","price":7.86,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/04722-49_22feea89-6bf0-4a2f-b1cb-83badb8537db.png?v=1788872794","url":"https:\/\/inter-pace.com\/products\/ohlins-o-ring-31-2x2-4-nbr-04722-49","provider":"Inter-Pace","version":"1.0","type":"link"}
