A leaking damper is not a cosmetic problem: it is a damper that has stopped controlling the wheel.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eInner Diameter 14 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 21026-02\u003c\/li\u003e\n\u003cli\u003eOuter Diameter 36 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eÖhlins gives it as 14 mm, 36 mm; nothing about that is approximate. Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position. Dust seals keep grit off the running surface; once they are torn, the oil seal behind them has a short life. Head diameter and thread are specific to the tube it closes.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. If you are between two sizes, send us the measurement and we will check it against the catalogue. We can supply the whole position from the drawing rather than the single piece if that is easier.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21026-02 in this case. Check inner diameter 14 mm, outer diameter 36 mm against what you have removed; a close size is not the same part. Static seals and dynamic seals are not interchangeable even in the same size. 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\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eWe are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.\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 21026-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Seal Heads\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 36 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":53652480327946,"sku":"21026-02","price":59.87,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21026-02_ae18db18-9be1-4224-87fc-6f73180cb3e8.png?v=1788879346","url":"https:\/\/inter-pace.com\/products\/ohlins-seal-head-14-36-21026-02","provider":"Inter-Pace","version":"1.0","type":"link"}
