All MVQ and VMQ O-rings available

Here you can find all the VMQ O-rings we have on stock at our shop. We offer these O-rings as standard from 60 to 90 Shore. these MVQ O-rings can handle temperatures from -60 °C to +200 °C. You can achieve +230 °C with special qualities. We offer those Sillicone O-rings in Red and Transparent.

The VMQ O-ring has a good resistant to:

• Water (max 100 °C)
• Ozone, weather conditions & aging
• Vegetable and animal oils and fat
• Aliphatic engine and gear oils

The VMQ O-ring is not resistant to:

• Aromatic minerals oils
• Steam over +120 °C
• Silicone oils and greases
• Fuels
• Acids & alkalis

What is VMQ Silicone (Polymethyl-Vinyl-Siloxanes)?

Dow Corning (a collaboration between Dow Chemicals and Corning Glass Company) was the first to produce silicone rubber. A few years later in 1947 General Electric also started the production of silicone rubber. They patented their production method. VMQ O-rings are a group of elastomeric materials made from silicones, oxygen, hydrogen, and carbon. As a group, silicones have poor tensile strength, tear-resistance, and abrasion resistance. Special compounds have been developed with exceptional resistance to heat and pressure changes. High-strength compounds have also been made, but their strength is not comparable to conventional rubber.

What is VMQ Silicone O-rings used for?

• Medical industry
• Farmaceutical industry
• Food industry

The advantages of an O ring from VMQ Silicone:

• It has a temperature working range from -40 °C to +200 °C
• Even at high temperatures, its characteristics won’t be affected
• Resistant to bacteria and fungi
• Excellent resistance to chemical fluids

The disadvantages of an O-ring from VMQ Silicone:

• Low resistance against mineral oils
• Not resistant to (aromatic) hydrocarbon, based fuels, and strong acids and alkalis
• It’s known for its mechanical weakness
• Sensitive to shear forces and therefore not suitable for dynamic or rotary closure application
