What is Food grade silicone o-ring?

Food grade silicone o-ring is a specialized o-ring made from  high-quality silicone rubber that are safe for use in food contact applications. These o-rings are non-toxic, non-reactive, and resistant to high temperatures, ideal used in food and beverage processing equipment, as well as in medical devices, pharmaceutical manufacturing, and other applications where purity and safety are critical.

When choosing a food grade silicone o-ring, it's important to look for a product that is FDA-approved for use in food contact applications. This ensures that the o-ring has been stricly tested and certified to be safe for use in food processing and manufacturing.

Applications of Silicone O-rings

Silicone O-rings are commonly used in hydraulic and pneumatic systems, automotive engines, and plumbing applications to prevent leaks and ensure a tight seal. Silicone O-rings are often preferred over other types of O-rings because of their ability to withstand high temperatures, as well as their flexibility and durability.

Pros and cons of silicone O-rings

First, maybe the biggest defining characteristic of silicone O-rings is their resistance to extreme temperatures. Capable of withstanding lows of -100°C and highs of up to 310°C, silicone O-rings can even tolerate even greater extremes for short periods of time.

Sencond, silicone O-rings are also extremely flexible, even in low ambient temperatures. They boast a low compression set as well, making them the perfect choice for compression force sealing and working among high temperatures and pressures.

Third, silicone O-rings boast tremendous resilience when exposed to ozone, acid, chemicals and oils. What’s more, the colour of the material used does not have any bearing on its effectiveness or capabilities, affording user greater aesthetic control when selecting the design of the O-ring. Silicone can be matched to any RAL or Pantone number.

Cons of silicone o-rings - Their tensile strength is not as accomplished as certain other materials and they are prone to suffering damage from tears and abrasions. This makes them more suited to static applications than dynamic ones, since a moving part is more likely to rupture their surface. Similarly, they are not the best choice in situations exposed to naked flames and they do not offer as robust impermeability as some other O-ring materials.
