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\u003eInner Diameter 36.1 mm\u003c\/li\u003e\n\u003cli\u003eCross Section 3.53 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00438-19\u003c\/li\u003e\n\u003cli\u003eMaterial NBR 70\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003e36.1 mm, 3.53 mm, NBR 70: that is the whole specification, and it has to match what came out. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure. A leaking damper is not a cosmetic problem: it is a damper that has stopped controlling the wheel. Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. Suspension is one of the few areas where the original part is genuinely the cheaper decision. The exploded drawing for your unit names the number; if you do not have it, we do. If you are between two sizes, send us the measurement and we will check it against the catalogue.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eOrder under 00438-19. Where several sizes share a description, only the number separates them. The published dimensions are inner diameter 36.1 mm, cross section 3.53 mm, material NBR 70 — measure the old part against them if you are unsure. The groove does half the work: the ring only seals if the groove is clean and undamaged. Size is given as inner diameter and cross-section; a close size is not a match.\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 00438-19\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 36.1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 3.53 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":53648797204746,"sku":"00438-19","price":7000.0,"currency_code":"PYG","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00438-19_ea80b252-f9b5-4770-b9c8-92c4550346c5.png?v=1788871922","url":"https:\/\/inter-pace.com\/en-py\/products\/ohlins-o-ring-36-1x3-53-nbr-70-00438-19","provider":"Inter-Pace","version":"1.0","type":"link"}
