Seal heads combine the oil seal, the dust seal and the bushing in one assembly. An O-ring seals by being squeezed into its groove; the cross-section is therefore as important as the diameter. 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\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. The exploded drawing for your unit names the number; if you do not have it, we do. Send us the model and serial number of your unit and we will confirm the position before you order.\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 — 00438-97 in this case. Öhlins states inner diameter 29 mm, cross section 2 mm, material NBR 70 for this number, and those figures are the deciding ones. Size is given as inner diameter and cross-section; a close size is not a match. 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\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 00438-97\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e O-Rings\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 29 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eMaterial:\u003c\/em\u003e NBR 70\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":53646903574794,"sku":"00438-97","price":2.0,"currency_code":"BAM","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-97_ad7b6389-cf7a-4efa-a47b-052f175daf18.png?v=1788869454","url":"https:\/\/inter-pace.com\/en-ba\/products\/ohlins-o-ring-29x2-nbr-70-00438-97","provider":"Inter-Pace","version":"1.0","type":"link"}
