Metric O-Rings

Metric O-rings are circular elastomer seals manufactured using metric sizing standards, designed to create an effective seal between two mating surfaces. They are commonly used to prevent the leakage of liquids, gases and pressure in hydraulic and pneumatic systems. Metric O rings are available in a variety of materials including NBR, FKM, EPDM and polyurethane, allowing them to perform in different temperatures, pressures and chemical environments. Their simple yet highly effective design makes them one of the most widely used sealing components across engineering, manufacturing and automotive industries. As experienced metric O ring suppliers, Swan Seals offers an extensive range of metric O rings online to support a wide variety of sealing applications.

There are many types of metric O rings available depending on the application requirements and operating conditions. Popular material options include NBR for excellent oil and fuel resistance, FKM for high-temperature and chemical applications, and polyurethane for enhanced durability, abrasion resistance and demanding industrial environments. Swan Seals supplies metric O rings in a variety of materials and sizes to suit hydraulic, pneumatic and engineering applications. Customers can purchase individual seals in a wide range of metric sizes or choose a metric O ring set containing commonly used dimensions for maintenance and repair work. A metric O ring kit is also a practical solution for engineers and workshops requiring quick access to multiple seal sizes in one organised collection. Swan Seals supplies metric O rings online in a variety of materials and hardness ratings to suit industrial, automotive and commercial applications.

Metric O-rings are used across numerous industries where reliable sealing performance is essential. Common applications include hydraulic systems, pneumatic equipment, pumps, valves, compressors, automotive components and industrial machinery. Their ability to provide dependable sealing against oils, fuels, air and fluids makes metric O rings suitable for both static and dynamic sealing applications. Metric O ring kits are particularly useful for maintenance engineers and technicians carrying out
servicing, repairs and emergency replacements across a range of equipment types. By supplying high-quality metric O rings online, Swan Seals supports industries requiring durable and cost-effective sealing solutions.

Choosing the correct metric O-ring depends on several key
factors including internal diameter, cross-section size, operating pressure, temperature range and media compatibility. Selecting the right material is essential for ensuring long-lasting sealing performance and preventing premature wear or leakage. NBR metric O rings are commonly used for oil and fuel applications, while FKM offers superior resistance to chemicals and high temperatures. For workshops and maintenance teams, a metric O ring kit can provide a convenient and economical solution for covering a broad range of sealing requirements.
