Öhlins uses a piston band rather than metal-to-metal contact, which is what keeps the bore intact.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eDimension A 6.3 mm\u003c\/li\u003e\n\u003cli\u003eDimension B 2.2 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 05402-08\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003e6.3 mm, 2.2 mm: that is the whole specification, and it has to match what came out. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design. Port area and shim seat geometry decide the damping curve before any adjuster is touched.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThe part is identical to what Öhlins fits in production — same supplier, same specification. Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. 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. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eOrder under 05402-08. Where several sizes share a description, only the number separates them. Öhlins states dimension a 6.3 mm, dimension b 2.2 mm for this number, and those figures are the deciding ones. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp. Port area and shim seat geometry decide the damping curve before any adjuster is touched.\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 05402-08\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Check Valves\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 6.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 2.2 mm\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":53649166139658,"sku":"05402-08","price":28000.0,"currency_code":"CDF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05402-08_afc755c0-cf23-4209-8ef6-e09bdfdf4208.png?v=1788874071","url":"https:\/\/inter-pace.com\/en-cd\/products\/ohlins-check-valve-dia-6-3-2-2-05402-08","provider":"Inter-Pace","version":"1.0","type":"link"}
