These O-rings are fully tested and certified to USP Class VI standards, making them ideal for use in pharmaceutical, medical device, and biotechnology applications.
Key Features & Benefits
USP Class VI certified
Fully tested and approved for use in pharmaceutical, medical, and biotech applications requiring biocompatibility and safety.
Wide Temperature Range
Capable of operating in a temperature range from -60°C to +250°C, making them suitable for cryogenic to high-temperature environments.
Chemical Resistance
Excellent resistance to alcohols, detergents, cleaning agents, polar chemicals, and mild acids commonly used in pharmaceutical processes.
Non-toxic and Non-Contaminating
VMQ silicone compounds are inherently non-toxic, non-reactive, and produce zero leachables, ensuring safe use in sensitive applications.
Excellent Compression Set Resistance
Maintains sealing force over long-term use, reducing the need for frequent replacements and minimizing maintenance costs.
