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\u003eInner Diameter 37 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00338-54\u003c\/li\u003e\n\u003cli\u003eMaterial FKM 70\u003c\/li\u003e\n\u003cli\u003eCross Section 2 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eThis one measures 37 mm, 2 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. The groove does half the work: the ring only seals if the groove is clean and undamaged. The dust seal does the hard work: it keeps the grit that would score the shaft away from the oil seal.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Öhlins keeps service parts available for units long after they leave the current price list. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e00338-54 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states inner diameter 37 mm, cross section 2 mm, material FKM 70 for this number, and those figures are the deciding ones. O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match. A ring that has taken a set no longer springs back and starts to weep under pressure.\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 00338-54\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 37 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 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":53648746578186,"sku":"00338-54","price":16.0,"currency_code":"BBD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00338-54_471e5b07-a91a-4434-abec-2baaeea98499.png?v=1788871708","url":"https:\/\/inter-pace.com\/en-bb\/products\/ohlins-o-ring-37x2-fkm70-00338-54","provider":"Inter-Pace","version":"1.0","type":"link"}
