An oil seal that has hardened lets the shaft pass oil past it, and the damping fades long before the leak becomes visible.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eCross Section 5 mm\u003c\/li\u003e\n\u003cli\u003eInner Diameter 40 mm\u003c\/li\u003e\n\u003cli\u003eMaterial FKM 70\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00438-27\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eDimensionally this is 40 mm, 5 mm, FKM 70, which is how it is told apart from the rest of the range. Assembly grease matters — the wrong compound swells the seal and it fails early. Seal heads combine the oil seal, the dust seal and the bushing in one assembly. Seal kits gather the pieces one rebuild needs, which avoids a second order mid-job.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eBuying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Öhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. For a full rebuild, the seal kit plus the wear parts is usually the sensible order. Öhlins parts are unit-specific: a close dimension is not a substitute.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003e00438-27 is the Öhlins number for this position — the same one printed in the service documentation. inner diameter 40 mm, cross section 5 mm, material FKM 70 is what distinguishes this number from its neighbours in the range. Seal kits gather the pieces one rebuild needs, which avoids a second order mid-job. The groove does half the work: the ring only seals if the groove is clean and undamaged.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 00438-27\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 40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eMaterial:\u003c\/em\u003e FKM 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":53646899937546,"sku":"00438-27","price":500.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-27_20e18e4a-30d7-4837-9aea-053ed2af76cf.png?v=1788869390","url":"https:\/\/inter-pace.com\/en-ph\/products\/ohlins-o-ring-40x5-00438-27","provider":"Inter-Pace","version":"1.0","type":"link"}
