What is O-ring cord?

O-ring cord, also known as rubber rope, is a commonly used sealing material used to seal joints against leakage of fluids or gases. This flexible cord is manufactured from high-quality materials such as silicone rubber, EPDM, nitrile rubber, and fluoro rubber, and has a round cross-section. Rubber cord is custom-cut and then closed in a circular shape to form a sealing ring that perfectly fits the specific application.

Thanks to the flexibility and resilience of the material, O-ring cord can effectively seal, even with slight deformations or irregularities in the surfaces to be joined. This makes it ideal for use in diverse industries, including automotive, construction, mechanical engineering, aviation, and more. Rubber cord is available in various diameters, hardnesses, and materials, making it suitable for a wide range of applications and environments.

What are the benefits of O-ring cord?

O-ring cord offers a range of benefits that make it a commonly used choice for sealing purposes in various industries. Thanks to the flexibility and resilience of the material, rubber cord easily adapts to different surfaces, providing effective sealing even with slight deformations or irregularities. This prevents leaks of fluids or gases, resulting in improved reliability of systems and equipment.

Additionally, O-ring cord offers excellent resistance to various environmental factors, such as temperature variations, chemicals, and pressure conditions. This makes it suitable for use in heavy industrial environments. Moreover, we can custom vulcanize rubber cords, ensuring even better performance and durability.

Applications of Rubber Round

Cord Round cord, also known as O-ring cord, finds a wide range of applications in various industries due to its versatility and effectiveness as a sealing material. It is used to seal joints against leakage of fluids, gases, and other media. In the automotive sector, round cord is used in engine parts, fuel systems, and hydraulic systems. In the construction industry, it is used for plumbing, piping, and ventilation systems. It is also indispensable in aviation, medical equipment, food processing, and HVAC systems.

Thanks to the flexibility and resilience of the material, o-ring cord adapts well to different surfaces, ensuring reliable sealing even under pressure or temperature variations. With various materials, sizes, and diameters available, rubber rope can be tailored to specific project requirements. It offers durable and efficient sealing solutions for various industrial applications.

The drawbacks of O-ring Cord

Although o-ring cord offers many advantages as a sealing material, there are also some drawbacks to consider. Firstly, the use of round cord in some applications may be limited due to the limited degree of compression it can provide compared to other sealing solutions such as gaskets or seals. This can lead to reduced sealing efficiency in situations where very high compression is required.

Additionally, o-ring cord may be susceptible to wear and deformation with prolonged exposure to extreme temperatures, chemicals, or pressure conditions. In such cases, the lifespan of the round cord may be shortened, requiring more frequent replacement.

It is important to consider these drawbacks and choose the right sealing solution based on the specific requirements and environmental factors of the application.
