O-rings are indispensable components in many branches of industry. These small seals ensure that liquids and gases remain safely contained in systems, preventing leaks and system failures. Due to their versatility and different material requirements, it is important to choose the right supplier for specific applications. In this guide, you will learn what to consider when selecting O-rings and which German suppliers specialize in high-quality O-rings.
O-rings are circular seals that are available in various materials such as rubber, silicone, Viton and other elastomers. They are often used to prevent leaks in systems and ensure a reliable seal. Due to their shape and elasticity, they adapt to the surfaces to be sealed and thus ensure an effective seal even under pressure.
O-rings are used in a wide range of applications, including:
Several factors come into play when choosing the right supplier for O-rings. Here are the most important considerations:
O-rings are available in various materials, which should be selected depending on the area of application. Commonly used materials are
Understanding the specific chemical and temperature resistance requirements is critical to selecting the right O-ring material. Suppliers should offer a wide range of materials and have the expertise to advise on material selection.
