Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure. An O-ring seals by being squeezed into its groove; the cross-section is therefore as important as the diameter. The groove does half the work: the ring only seals if the groove is clean and undamaged.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. Order by part number — descriptions repeat across sizes, numbers do not. Where a number has been superseded, Öhlins states the replacement — we pass that on.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003e00338-72 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states inner diameter 27.1 mm, cross section 1.6 mm, material NBR 70 for this number, and those figures are the deciding ones. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages. Öhlins specifies the compound by position: NBR where oil is the concern, FKM where heat is.\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 00338-72\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 27.1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 1.6 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":53646887321866,"sku":"00338-72","price":500.0,"currency_code":"XOF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00338-72_290ea928-e4d2-404c-872a-2636566e557a.png?v=1788869206","url":"https:\/\/inter-pace.com\/en-bf\/products\/ohlins-o-ring-27-1x1-6-00338-72","provider":"Inter-Pace","version":"1.0","type":"link"}
