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. Öhlins specifies the compound by position: NBR where oil is the concern, FKM where heat is.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Öhlins publishes dimensions for its service parts so a workshop can verify before it fits. Tell us the damper's model designation and year and we will match the number for you. The exploded drawing for your unit names the number; if you do not have it, we do.\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 — 00438-50 in this case. Check inner diameter 33 mm, cross section 2 mm, material NBR 70 against what you have removed; a close size is not the same part. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost. An O-ring seals by being squeezed into its groove; the cross-section is therefore as important as the diameter.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\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 00438-50\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 33 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":53646901084426,"sku":"00438-50","price":100.0,"currency_code":"MKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-50_78c11279-fa49-4048-b91d-cb100904ffbf.png?v=1788869413","url":"https:\/\/inter-pace.com\/en-mk\/products\/ohlins-o-ring-33x2-nbr70-00438-50","provider":"Inter-Pace","version":"1.0","type":"link"}
