Silicone O-ring Advantages
-
Silicone rubber makes the ideal material for O-rings, as it is flexible, stable, non-reactive, and capable of withstanding high temperatures and extreme environmental conditions. Heat-resistant silicone O-rings are resistant to a temperature range of up to 310° C or 590° F and as low as -100° C or -148° F. In limited circumstances, they may also exceed those tolerances for short durations.
- Silicone O-rings also exhibit a low compression set, meaning they are ideal for compression force sealing and applications where high pressures or temperatures exist. These highly resilient components are also resistant to chemicals, acids, alkali, and ozone. In industries where esthetics is a factor, silicone O-rings can be matched to any RAL or Pantone number for a highly customized look.
Additional Advantages Include
- Odorless, tasteless, and non-toxic
- Easy to manufacture
- Outstanding oil resistance at high temperatures
- Superior dielectric properties and high thermal resistance
- Suitable alternative to more expensive materials like fluorocarbon, nitrile, and PTFE
- Can be reinforced with inert fillers to increase certain mechanical properties without negatively impacting performance
- Resistant to ketones, weathering, fungal growth, dry heat, and sunlight
While the list of advantages of high-temperature O-rings is extensive, they are subject to some limitations. Silicone does not have the tensile strength of some alternative materials, nor does it have high resistance to tears and abrasions. This means that silicone O-rings are not well-suited for dynamic applications. Silicone is also more permeable than other materials, so it is not suitable for direct exposure to steam, fuel, or gear lubricants.

Applications Of Silicone Rings
With numerous beneficial characteristics, silicone rubber O-rings are the ideal sealing components for a wide variety of applications across many diverse industries. They perform well in environments where other materials may suffer, such as in dry heat. The superior electrical insulating properties of high-temperature O-rings make them highly desirable for applications subject to strict performance standards. Silicone rubber O-rings are also used in FDA-approved food handling equipment and appliances.
