Measure the old part against them before ordering. Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position. Assembly grease matters — the wrong compound swells the seal and it fails early. Seal heads combine the oil seal, the dust seal and the bushing in one assembly.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. Öhlins keeps service parts available for units long after they leave the current price list. We can supply the whole position from the drawing rather than the single piece if that is easier. If you are between two sizes, send us the measurement and we will check it against the catalogue.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 01651-04 in this case. The published dimensions are inner diameter 12 mm, outer diameter 37.2 mm, thickness 25 mm — measure the old part against them if you are unsure. Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages.\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 01651-04\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 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 37.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThickness:\u003c\/em\u003e 25 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":53649129111818,"sku":"01651-04","price":467.7,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/01651-04_e248e5df-0b92-404e-8ed9-6a7da2cf66ca.png?v=1788873884","url":"https:\/\/inter-pace.com\/en-dk\/products\/ohlins-seal-head-front-fork-12-37-2-25-01651-04","provider":"Inter-Pace","version":"1.0","type":"link"}
