Seals are the part of a damper that decides whether it holds its gas charge and its oil, and they are the usual reason a unit ends up on the bench.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCross Section 2 mm\u003c\/li\u003e\n\u003cli\u003eInner Diameter 17 mm\u003c\/li\u003e\n\u003cli\u003eMaterial NBR 70\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00338-40\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eThe published figures are 17 mm, 2 mm, NBR 70. Measure the old part against them before ordering. O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match. O-rings are single-use in a pressurised damper — they are replaced whenever the unit is opened. Seal heads combine the oil seal, the dust seal and the bushing in one assembly.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up. Order by part number. The dimensions below are the ones Öhlins publishes for it.\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 — 00338-40 in this case. The published dimensions are inner diameter 17 mm, cross section 2 mm, material NBR 70 — measure the old part against them if you are unsure. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost. A seal that has taken a set no longer springs back and starts to weep.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 00338-40\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 17 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 2 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":53646885454090,"sku":"00338-40","price":7.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00338-40_ac5ce7c1-fa39-4c77-ae4a-f8e9ad0f1543.png?v=1788869167","url":"https:\/\/inter-pace.com\/en-hk\/products\/ohlins-o-ring-17x2-nbr70-00338-40","provider":"Inter-Pace","version":"1.0","type":"link"}
