O-Ring Cord

O ring cord is a continuous length of elastomer sealing material designed to be cut and joined to create custom-sized O-rings. Commonly referred to as seal cord or o ring rubber cord, it is used in applications where non-standard dimensions are required or where rapid on-site sealing solutions are needed. O ring cord stock is available in a range of diameters and materials to suit different operating conditions, including resistance to oils, chemicals, pressure and high temperatures. Its flexibility and versatility make it a practical solution for maintenance engineers, manufacturers and repair operations requiring bespoke sealing components.

There are several types of o ring cord available depending on the application and operating environment. Swan Seals supplies NBR70 cord for general-purpose oil and fuel resistance, NBR90 cord for higher pressure applications, FKM75 cord for chemical and elevated temperature environments, and FKM90 cord for demanding industrial sealing conditions. These materials are available as o ring cord stock in various diameters, allowing customers to create cord for custom O rings to exact specifications. Rubber cord options can be selected based on flexibility, hardness, chemical compatibility and operating temperature requirements.

O ring rubber cord is widely used across hydraulic, pneumatic, automotive, manufacturing and engineering industries where custom sealing solutions are required. Seal cord is commonly used to manufacture bespoke O-rings for pumps, valves, cylinders, compressors and industrial machinery. It is particularly useful in maintenance and repair environments where replacement seals may be difficult to source or where downtime needs to be minimised. O ring cord stock also provides a cost-effective solution for low-volume production runs and specialist sealing applications requiring non-standard dimensions or material properties.

Choosing the correct o ring cord depends on factors including material compatibility, operating temperature, pressure levels and the diameter required for the finished seal. NBR rubber cord is commonly selected for oil and hydraulic fluid applications, while FKM seal cord is ideal for high-temperature and chemical-resistant environments. It is also important to choose the correct cord diameter to ensure the finished custom O-ring provides effective sealing performance. Swan Seals offers a comprehensive range of o ring cord stock and cord for custom O rings, helping customers source durable and reliable sealing materials for industrial and engineering applications.
