An O-ring seals by being squeezed into its groove; the cross-section is therefore as important as the diameter.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMaterial NBR 70\u003c\/li\u003e\n\u003cli\u003eInner Diameter 20.3 mm\u003c\/li\u003e\n\u003cli\u003eCross Section 2.4 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00438-54\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eÖhlins publishes 20.3 mm, 2.4 mm, NBR 70 for 00438-54 — the dimensions are the identity of the part. An oil seal that has hardened lets the shaft pass oil past it, and the damping fades long before the leak becomes visible. The groove does half the work: the ring only seals if the groove is clean and undamaged. Öhlins specifies the compound by position: NBR where oil is the concern, FKM where heat is.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins keeps service parts available for units long after they leave the current price list. Öhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. If the unit is already apart, compare the published dimensions with the part in your hand. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e00438-54 is the Öhlins number for this position — the same one printed in the service documentation. inner diameter 20.3 mm, cross section 2.4 mm, material NBR 70 is what distinguishes this number from its neighbours in the range. Size is given as inner diameter and cross-section; a close size is not a match. O-rings are single-use in a pressurised damper — they are replaced whenever the unit is opened.\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 00438-54\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 20.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 2.4 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":53646901903626,"sku":"00438-54","price":100.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-54_08fa35b9-ca90-4560-b93d-d47b6a4774a8.png?v=1788869418","url":"https:\/\/inter-pace.com\/en-ph\/products\/ohlins-o-ring-20-3x2-4-nbr-70-00438-54","provider":"Inter-Pace","version":"1.0","type":"link"}
