Replacing the head as a unit is usually faster and more reliable than fitting the seals individually.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 21025-09\u003c\/li\u003e\n\u003cli\u003eInner Diameter 14 mm\u003c\/li\u003e\n\u003cli\u003eOuter Diameter 36 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eThe published figures are 14 mm, 36 mm. Measure the old part against them before ordering. The bushing inside carries the side load so the seal only has to seal. Assembly grease matters — the wrong compound swells the seal and it fails early. Head diameter and thread are specific to the tube it closes.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins manufactures service parts on the same lines as production parts — there is no second quality. Suspension is one of the few areas where the original part is genuinely the cheaper decision. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21025-09. inner diameter 14 mm, outer diameter 36 mm is what distinguishes this number from its neighbours in the range. Assembly grease matters — the wrong compound swells the seal and it fails early. Öhlins uses seals with a spring-loaded lip so they follow the shaft as it wears.\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 21025-09\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":53652479508746,"sku":"21025-09","price":113700.0,"currency_code":"XOF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21025-09_a3624d76-cc20-450e-936c-8d687fb03f8f.png?v=1788879344","url":"https:\/\/inter-pace.com\/en-ml\/products\/ohlins-seal-head-assy-14-36-21025-09","provider":"Inter-Pace","version":"1.0","type":"link"}
