Silicone O-Rings (VMQ)
Silicone O-Rings (VMQ) for high and low temperature static sealing (-60°C to +230°C), widely used in food processing and medical equipment. Available in standard and custom sizes with OEM manufacturing support.
Product overview
Product details
Silicone O-Rings (VMQ) are made from silicone rubber, providing superior thermal stability and flexibility for static sealing applications.
They are widely used in food processing equipment, medical devices, and industrial machinery where high and low temperature resistance is required.
Key Features
- Excellent performance in extreme temperatures (-60°C to +230°C)
- Outstanding flexibility and elasticity for reliable sealing
- Excellent ozone and weather resistance
- Suitable for food-grade and medical applications
- Non-toxic, odorless, and environmentally stable
Technical Specifications
- Material: Silicone (VMQ)
- Temperature Range: -60°C to +230°C
