The groove does half the work: the ring only seals if the groove is clean and undamaged. Öhlins uses seals with a spring-loaded lip so they follow the shaft as it wears. A seal that has taken a set no longer springs back and starts to weep.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins publishes dimensions for its service parts so a workshop can verify before it fits. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. We can check the number against the Öhlins exploded view before you order — just ask. If the unit is already apart, compare the published dimensions with the part in your hand.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eOrder under 00438-34. Where several sizes share a description, only the number separates them. Check inner diameter 57.8 mm, cross section 1.6 mm, material NBR 70 against what you have removed; a close size is not the same part. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages. The dust seal does the hard work: it keeps the grit that would score the shaft away from the oil seal.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eAsk us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.\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 00438-34\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 57.8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 1.6 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":53646900265226,"sku":"00438-34","price":30000.0,"currency_code":"PYG","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-34_0a580abc-4a21-421e-9cdb-daaa731dd1d6.png?v=1788869398","url":"https:\/\/inter-pace.com\/en-py\/products\/ohlins-o-ring-57-8x1-6-nbr70-00438-34","provider":"Inter-Pace","version":"1.0","type":"link"}
