Oring 76x3 MVQ 70 ShA - silicone O-ring high temperature seal

Construction and material properties

Oring 76x3 MVQ 70 ShA is made from silicone rubber MVQ, a high-performance elastomer designed for applications requiring wide temperature resistance and long-term stability. Compared to standard NBR O-rings, silicone offers superior flexibility in both very low and very high temperatures.

The 70 ShA hardness provides a balanced combination of elasticity and mechanical strength, ensuring reliable sealing in static and light dynamic applications. The 3 mm cross-section allows stable sealing performance in medium and larger assemblies.

Key material properties:

• temperature range: from -60 to +200 C
• excellent resistance to UV and ozone
• high flexibility in extreme conditions
• strong resistance to aging and weathering
• suitable for outdoor and thermal applications

Industrial applications

Oring 76x3 MVQ is widely used in industries where temperature resistance and environmental durability are critical. It is especially effective in applications where standard elastomers cannot maintain performance.

Typical applications include:

• food processing and handling equipment
• heating systems and high temperature installations
• HVAC and ventilation systems
• medical and laboratory equipment
• outdoor sealing exposed to UV and weather

In specific material formulations, silicone MVQ can be used in applications requiring compliance with food contact regulations such as FDA.
