Product Introduction

Rubber O-rings are circular sealing components made of rubber that are designed to fit into a groove, creating a tight seal between two or more mechanical components. Rubber o-rings are popular sealing solutions because of their simplicity, durability and versatility.
Rubber O-rings are an effective sealing solution for preventing leaks in various mechanical applications. They come in different sizes, materials, and temperature and pressure resistance, providing versatility and adaptability for a wide range of applications in industries such as automotive, aerospace, and industrial manufacturing.

Product Features

1. Material: Rubber O-rings are made from different materials depending on the application requirements. Common materials used include nitrile rubber, silicone rubber, viton rubber, and EPDM rubber.
2. Size: Rubber O-rings come in a variety of sizes and diameters, making them useful for sealing both large and small components.
3. Temperature Resistance: Rubber O-rings are designed to operate in a wide range of temperatures, from very low to very high. Temperature resistance varies by material and can range from -40°C to 300°C or more.
4. Pressure Resistance: Rubber O-rings can withstand pressure ranging from low to high because of its natural elasticity, which allows it to expand and contract without causing damage to the seal.
5. Chemical Resistance: Rubber O-rings are resistant to chemicals found in various fluids like oils, fuels, and solvents, and are resistant to corrosion, making them long-lasting.
6. Durability: Rubber O-rings can provide long-lasting durability and reliability even in harsh environments due to its resistant properties.
