Leaky pipes. Malfunctioning engines. What\u2019s the common culprit? A worn-out O-ring seal.<\/strong>
\nO-rings are small but essential\u2014preventing leaks, saving costs, and ensuring safety.<\/p>\n

O-ring seals work by compressing between two surfaces to block gas or liquid leakage.<\/strong> They're used in engines, valves, pumps, and more.<\/p>\n

This guide breaks down O-ring materials, failures, applications, and how to choose the best one\u2014based on real use cases.<\/p>\n

O-Ring Contas\u0131n\u0131n Amac\u0131 Nedir?<\/h2>\n

O-rings fill the gap between two surfaces to form a pressure-tight seal.
\nThey\u2019re the most widely used seals in industrial and automotive systems.<\/p>\n

They prevent gas, oil, and air from escaping\u2014even under pressure or vibration.<\/strong><\/p>\n

O-rings are popular because they\u2019re simple, cheap, and effective. Compared to other sealing methods, they\u2019re easier to install and require less space.

What\u2019s the Difference Between an O-Ring and a Gasket?<\/h2>\n

Both prevent leaks, but they work differently.<\/p>\n

O-ringler<\/strong> fit into a groove and seal by deformation under pressure.
\nContalar<\/strong> are flat and compress between two surfaces.<\/p>\n

Use an O-ring when your system involves dynamic movement, high pressure, or rotary components.

Which O-Ring Material Should You Choose?<\/h2>\n

Different materials mean different performance.<\/p>\n

NBR (nitrile)<\/strong> resists oil well. FKM (Viton)<\/strong> handles heat and chemicals. EPDM<\/strong> suits steam and outdoor use. Silikon<\/strong> works in extreme temperatures.<\/p>\n
