O-Rings

Silicone O-Ring

Silicone (VMQ) O-rings offer outstanding temperature resistance and excellent flexibility across a wide temperature range. They are non-toxic, odorless, and physiologically inert, making them ideal for food machinery, biopharmaceutical equipment, and medical devices. Our silicone O-rings are produced in a clean room environment to ensure contamination-free quality for high-purity applications.
