The groove does half the work: the ring only seals if the groove is clean and undamaged.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCross Section 1.78 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00338-44\u003c\/li\u003e\n\u003cli\u003eMaterial FKM 70\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eInner Diameter 3.68 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eThis one measures 3.68 mm, 1.78 mm, FKM 70, and those figures are what separate it from the neighbouring numbers. Assembly grease matters — the wrong compound swells the seal and it fails early. A leaking damper is not a cosmetic problem: it is a damper that has stopped controlling the wheel. Seal heads combine the oil seal, the dust seal and the bushing in one assembly.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins publishes dimensions for its service parts so a workshop can verify before it fits. Suspension is one of the few areas where the original part is genuinely the cheaper decision. Öhlins parts are unit-specific: a close dimension is not a substitute. If you are between two sizes, send us the measurement and we will check it against the catalogue.\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 — 00338-44 in this case. Check inner diameter 3.68 mm, cross section 1.78 mm, material FKM 70 against what you have removed; a close size is not the same part. O-rings are single-use in a pressurised damper — they are replaced whenever the unit is opened. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost.\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 00338-44\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 3.68 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 1.78 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":53646885683466,"sku":"00338-44","price":7000.0,"currency_code":"PYG","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00338-44_80e45f43-20f2-4656-8c36-4fa35c425bc8.png?v=1788869173","url":"https:\/\/inter-pace.com\/en-py\/products\/ohlins-o-ring-3-68x1-78-fkm70-00338-44","provider":"Inter-Pace","version":"1.0","type":"link"}
