O-ring

In the world of industry, good sealing is essential to ensure the reliability of equipment. Simple and effective, the O-ring is a strategic component. Seals are used in plumbing, as well as in maintenance, aerospace, machining, and food processing. With a construction of rubber, elastomer, or other materials, it features a circular shape to adapt to numerous applications. The wide range from Rubix provides quality solutions to meet the diverse needs of industrial professionals.

The O-ring, known as an O-ring, is characterised by its simple ring shape with a circular cross-section, a toroidal shape capable of deforming under compression. This ability allows it to block the passage of liquids or gases. It is used in both static assemblies and dynamic systems such as cylinders. The various references are distinguished by characteristics such as inner diameter, thickness of the torus, material, and hardness.

Thanks to its great versatility, the O-ring is essential in various environments. This circular sealing joint ensures the sealing of pumps, cylinders, and fittings with hydraulic or pneumatic devices. In water and steam networks, it protects equipment against leaks.

It is also found in machining or surface treatment machines to extend the lifespan of components. Among the main users of O-rings are the aerospace, food processing, plumbing, and automotive sectors. It helps secure installations and enhance process reliability.

The Rubix catalogue includes a range of O-rings that meet multiple needs, even the most specific:

• Models for static applications ensure fixed sealing of covers or flanges.
• Versions compatible with slow movements are reinforced with support rings.
• Variants coated with FEP or PTFE guarantee high chemical resistance.

Rubix collaborates with renowned manufacturers to offer the best quality. Professionals thus have access to numerous sizes and references to meet all constraints.

The brand DICHTOMATIK offers standardised seals in NBR, FKM, or PTFE. Meanwhile, ANYSEALS stands out with its O-rings, X-rings, ANYSEALS stands out with its O-rings, kits and cords. The company Sandvik Coromant integrates its seals into machining systems for greater efficiency. Finally, the French company Hutchinson provides robust solutions in industrial rubber seals designed for harsh environments.

The longevity of an O-ring depends on important conditions such as temperature, pressure, and the fluid in contact. Materials play a central role and are tailored for specific uses. Each of them comes in different hardness levels and is measured in shore (70–90) to assess operating constraints.

• Nitrile ensures good results in hydraulic applications. It is versatile and offers a good cost/performance compromise.
• In addition to excellent chemical resistance, PTFE has a low coefficient of friction.
• FKM withstands high temperatures, as well as aggressive oils, fuels, and solvents.
• FFKM is specifically designed for severe chemical environments.
• EPDM is suitable for hot water and steam.
• Silicone supports wide thermal amplitudes.

To further preserve the lifespan of the seal, appropriate storage and controlled installation are essential parameters.

Careful preparation is mandatory before installing your seal. The surfaces and chamfers must be perfectly clean. The application of a lubricant facilitates the operation and avoids unnecessary effort.

During assembly, it is important to avoid twisting and pinching to maintain a good position. Once these steps are completed, perform a compression check to ensure a durable seal. This ensures reliable operation and optimal lifespan.

The selection of a suitable O-ring is based on several criteria:

• Verification of dimensions;
• Identification of the fluid in contact and the temperature range;
• Measurement of pressure levels and mechanical constraints;
• Static assembly or dynamic applications;
• Evaluation of roughness and surface treatment of the housing;
• Determining the appropriate material and hardness.

As an essential sealing solution, the O-ring is a sealing joint that must be chosen carefully according to the application. From material to size, it must be suited to the application. With Rubix, professionals benefit from technical expertise and a varied stock to secure their installations sustainably.
