The groove does half the work: the ring only seals if the groove is clean and undamaged. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages. Static seals and dynamic seals are not interchangeable even in the same size.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins manufactures service parts on the same lines as production parts — there is no second quality. Öhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. The Öhlins exploded view names the number for each position; we can look it up if you do not have it.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e00638-65 is the Öhlins number for this position — the same one printed in the service documentation. Check inner diameter 34.29 mm, cross section 5.33 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. Assembly grease matters — the wrong compound swells the seal and it fails early.\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 00638-65\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 34.29 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 5.33 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":53648924836106,"sku":"00638-65","price":9.68,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00638-65_ac7b6267-4b9c-479a-908f-f67374deead3.png?v=1788872638","url":"https:\/\/inter-pace.com\/products\/ohlins-o-ring-34-29x5-33-nbr70-low-temp-00638-65","provider":"Inter-Pace","version":"1.0","type":"link"}
