Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eMaterial NBR 70\u003c\/li\u003e\n\u003cli\u003eCross Section 2 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00438-43\u003c\/li\u003e\n\u003cli\u003eInner Diameter 58 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003e00438-43 is the 58 mm, 2 mm, NBR 70 version — Öhlins lists each size separately. Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position. Seal heads combine the oil seal, the dust seal and the bushing in one assembly. 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\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Rebuilding to specification only works if the parts are to specification — that starts here. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eOrder under 00438-43. Where several sizes share a description, only the number separates them. Check inner diameter 58 mm, cross section 2 mm, material NBR 70 against what you have removed; a close size is not the same part. Öhlins uses seals with a spring-loaded lip so they follow the shaft as it wears. Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position.\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 00438-43\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 58 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":53646900756746,"sku":"00438-43","price":1.29,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-43_06ca7de8-e556-42aa-ab09-b4ecfb2a7f91.png?v=1788869405","url":"https:\/\/inter-pace.com\/en-tr\/products\/ohlins-o-ring-58x2-nbr70-00438-43","provider":"Inter-Pace","version":"1.0","type":"link"}
