Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure. Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks. Head diameter and thread are specific to the tube it closes.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. 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\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21026-05 in this case. Öhlins states inner diameter 14 mm, outer diameter 36 mm for this number, and those figures are the deciding ones. The bushing inside carries the side load so the seal only has to seal. Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position.\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 21026-05\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":53652480786698,"sku":"21026-05","price":93.26,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21026-05_1d7befd4-091b-4d93-bbe6-aabbd35524a4.png?v=1788879349","url":"https:\/\/inter-pace.com\/products\/ohlins-seal-head-14-36-21026-05","provider":"Inter-Pace","version":"1.0","type":"link"}
