What are Silicone O-rings?
Silicone o-rings are excellent seal materials for high temperatures in static environments. Typically, silicone o-rings show outstanding flex and fatigue life, strong ozone and UV radiation resistance, and physiologically neutral and insulating properties. Silicone o-rings can be synthesized with a wide variety of properties and compositions, allowing for great flexibility in performance.
Why Choose Our Silicone O-rings?
For more than 20 years, we have been offering custom and standard silicone o-rings and other sealing solutions for multiple industries. With millions of silicone o-rings produced and shipped annually, we are the experts your organization needs to seal the success of your application.
Applications of Silicone O-rings
Silicone o-rings are excellent seal materials for static, high temperature applications. Featuring outstanding flex and fatigue life, ozone and UV radiation resistance, physiologically neutral and insulating properties, silicone o-rings are effective in a wide range of applications. You can find the silicone o-ring for anything you need from us which are perfect for you.
Mechanical Properties
Silicone o-rings have poor wear resistance, excellent compression set resistance, poor short-term resilience and excellent permeation resistance.
How a Silicone O-Ring Works?
Silicone O-ring seals are capable of sealing at relatively high pressures because they are compressed or activated when pressurized – as the pressure is applied to the silicone o-ring it deforms in the gland or groove. As a silicone o-ring deforms between two flat and smooth surfaces, it presses into the gland walls and seal joint. The compression energizes the seal and creates a mechanical barrier blocking fluids from passing through; this restrained condition allows a silicone o-ring to seal at higher pressures than many flat face gaskets.
