Dust seals keep grit off the running surface; once they are torn, the oil seal behind them has a short life.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 21754-03\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eThere is no measurement to check here — the number and the exploded view identify it. Head diameter and thread are specific to the tube it closes. Static seals and dynamic seals are not interchangeable even in the same size. Seal heads combine the oil seal, the dust seal and the bushing in one assembly.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eEvery part in this catalogue is one Öhlins fits itself during assembly and service. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. For a full rebuild, the seal kit plus the wear parts is usually the sensible order. Öhlins parts are unit-specific: a close dimension is not a substitute.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21754-03 in the exploded view for the unit it belongs to. Öhlins does not publish a dimension here — go by the number and the exploded view. Seal heads combine the oil seal, the dust seal and the bushing in one assembly. Static seals and dynamic seals are not interchangeable even in the same size.\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 21754-03\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Seal Heads\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":53652829241610,"sku":"21754-03","price":375.0,"currency_code":"QAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21754-03_a874b897-0b5b-439e-8c8c-19fcc391e98d.png?v=1788880185","url":"https:\/\/inter-pace.com\/en-qa\/products\/ohlins-seal-head-43-5-21754-03","provider":"Inter-Pace","version":"1.0","type":"link"}
