What Are Silicone Rubber O-Rings?

Silicone rubber O-rings are circular sealing components made from silicone elastomers, known for their excellent resistance to extreme temperatures, flexibility, and chemical stability. O-rings are used to create a seal between two surfaces to prevent the escape of liquids or gases. Due to the unique properties of silicone, these O-rings can be used in demanding environments where other materials may fail.

At Accuseal Rubber Inc, we produce silicone rubber O-rings that are available in various sizes, cross-sectional diameters, and custom formulations. Whether your application requires high-temperature performance, resistance to chemicals, or biocompatibility, we have the perfect O-ring solution for your needs.

Key Features and Benefits of Accuseal’s Silicone Rubber O-Rings

1. Wide Temperature Range:

One of the most important characteristics of silicone rubber O-rings is their ability to maintain performance across a broad temperature range. Our silicone O-rings can withstand temperatures as low as -80°F (-60°C) and as high as 500°F (260°C) without compromising their sealing capability. This makes them ideal for use in environments that experience extreme heat or cold, such as automotive engines, aerospace systems, and industrial furnaces.

2. Excellent Chemical Resistance:

Accuseal’s silicone rubber O-rings offer excellent resistance to a variety of chemicals, including acids, bases, oils, and solvents. This chemical resistance makes our O-rings suitable for use in industries such as chemical processing, pharmaceuticals, and food and beverage production, where contact with corrosive substances is common. The non-reactive nature of silicone ensures that our O-rings can maintain their integrity even when exposed to harsh chemicals over extended periods.

3. Flexibility and Elasticity:

Silicone is known for its superior flexibility and elasticity, making our O-rings ideal for sealing applications that require repeated movement or compression. The elasticity of our silicone O-rings ensures a tight, leak-proof seal even under conditions of constant pressure and temperature fluctuations. This flexibility also prevents the O-rings from cracking, tearing, or deforming over time, ensuring long-term reliability.

4. Biocompatibility and Non-Toxicity:

Silicone is a biocompatible material, making it an ideal choice for medical and food-grade applications. Our silicone rubber O-rings are manufactured using FDA-approved materials, ensuring they are non-toxic and safe for use in medical devices, food processing equipment, and pharmaceutical applications. In medical settings, these O-rings can be used in applications such as seals for pumps, fluid transfer systems, and diagnostic equipment, where cleanliness and safety are paramount.

5. UV, Ozone, and Weather Resistance:

Silicone rubber is highly resistant to environmental factors such as ultraviolet (UV) light, ozone, and moisture. This resistance makes our silicone O-rings an excellent choice for outdoor applications, including HVAC systems, outdoor lighting, and automotive components. The ability to resist UV degradation ensures that our O-rings can maintain their sealing properties even when exposed to harsh weather conditions.

6. Customizable Solutions:

At Accuseal Rubber Inc, we understand that each application has unique requirements. That’s why we offer extensive customization options for our silicone rubber O-rings. Whether you need a specific size, cross-sectional profile, hardness level, or color, we can provide tailor-made O-ring solutions to meet your exact specifications. We also offer specialty formulations, such as flame-retardant silicone or conductive silicone, for applications with unique performance demands.
