X-rings, also known as four-lobed seals, are elastomeric sealing elements designed for applications that require higher performance than a conventional o-ring. Their X-shaped cross-section creates four sealing lips that distribute contact pressure more evenly, reduce friction and prevent the seal from twisting in service.<\/p>
Thanks to their symmetrical design, x-rings can be used in both static and dynamic applications, delivering excellent sealing performance in hydraulic and pneumatic cylinders, shafts, valves, pumps, actuators, industrial automation systems and many other mechanical assemblies.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

At OSN we supply x-rings manufactured in a wide range of elastomeric compounds to suit different working conditions, temperatures and chemical compatibilities.<\/p>
NBR (nitrile) is the most widely used material for its excellent resistance to mineral oils, greases, fuels and hydraulic fluids, together with high tear resistance and an excellent price-performance ratio. FKM (Viton\u00ae) is particularly suited to high temperatures and aggressive chemical media, offering outstanding resistance to synthetic oils, aromatic hydrocarbons and many chemicals. For hot water, steam and weathering, EPDM is available, while for low temperatures or special applications we can supply VMQ (silicone), CR (neoprene), HNBR, FFKM and other technical elastomers on request.<\/p>
We also offer materials with specific approvals for the food, drinking water, pharmaceutical, chemical, oil and gas industries, as well as special formulations according to each project\u2019s requirements.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
