Silicone O-Ring (VMQ)

Description

Silicone O-rings are precision-molded sealing rings made from high-performance silicone rubber (VMQ). They are widely used in static and dynamic applications requiring exceptional temperature resistance, flexibility, and material purity.

Key Features

• Wide Temperature Range: Functions reliably from -60°C to +230°C (-76°F to +446°F), with excellent performance in both extreme cold and dry heat.

• Excellent Flexibility: Remains elastic and resilient at low temperatures, providing effective sealing even in cryogenic environments.

• High Material Purity: Inert, odorless, and tasteless, making them ideal for food, beverage, medical, and pharmaceutical applications (FDA compliant grades available).

• Good Compression Set Resistance: Maintains sealing force over time, especially in static applications.

• Physiologically Inert: Non-toxic and resistant to bacteria growth; suitable for sterile and biocompatible applications.

Typical Applications

• Food processing equipment

• Medical devices and pharmaceutical machinery

• Beverage dispensing systems

• HVAC systems and high-temperature drying equipment

• Aerospace and automotive sealing

• Laboratory and analytical instruments

Material Compatibility (Resists)
