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\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 22153-01\u003c\/li\u003e\n\u003cli\u003eOuter Diameter 40 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eInner Diameter 16 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eÖhlins gives it as 16 mm, 40 mm; nothing about that is approximate. 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. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins keeps service parts available for units long after they leave the current price list. Tell us the damper's model designation and year and we will match the number for you. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eOrder under 22153-01. Where several sizes share a description, only the number separates them. Check inner diameter 16 mm, outer diameter 40 mm against what you have removed; a close size is not the same part. A weeping damper almost always starts here. Öhlins builds the head so the dust seal takes the grit before it reaches the oil seal.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 22153-01\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 16 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 40 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":53653168488714,"sku":"22153-01","price":96.94,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/22153-01_232ff59c-684a-4147-aa18-1ad1878f847a.png?v=1788880629","url":"https:\/\/inter-pace.com\/products\/ohlins-seal-head-16-40-ttx-ar-x-assy-22153-01","provider":"Inter-Pace","version":"1.0","type":"link"}
