An O-rings are a sealing device in the shape of a torus designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface. In simple words, it is a loop of elastomer with a circular cross-section.

O-rings can be used in both static and dynamic applications. They are the most basic and effective seals ever invented as they are inexpensive, easy to make, reliable, and have simple mounting requirements.

By choosing a compound and hardness it is usually possible to find a suitable O-ring for most applications ranging from generators, compressors, gas-springs, automobiles, pumps & valves, actuators, hydraulic & pneumatic cylinders, filters, lubricating systems to LPG regulators.

We specialize in the manufacturing of Rubber O-rings from all types of Rubber Grades like Silicone, Viton®, EPDM, Nitrile, Neoprene, Natural & others.

MREW offers a wide array of metric sizes, in both standard and non-standard dimensions. If an O-ring with unique size or fluid resistance is required, MREW can customize the same specifically to your demanding requirements.

Beyond the standard O-ring, MREW can supply more advanced sealing designs such as Quad Rings® specially designed for low pressure sealing.
