Silicone O Ring 279.3x5.7 mm MVQ 70 ShA

Industrial Applications

Silicone O Ring 279.3x5.7 mm MVQ 70 ShA is a precision elastomer sealing element designed for industrial systems operating under wide temperature ranges and requiring stable chemical resistance. Silicone O Rings made from MVQ compound are widely used in industrial processing equipment, laboratory installations, food production systems and air handling units where conventional rubber materials may lose elasticity.

This size 279.3x5.7 mm silicone sealing ring is typically used in large diameter housings, covers, tanks and processing units where reliable static sealing is required. Silicone MVQ material performs well in environments with air, hot water, steam and moderate chemical exposure.

Silicone O Rings are commonly selected when applications require excellent flexibility at very low temperatures combined with stable mechanical performance at elevated temperatures.

Silicone O Ring 279.3x5.7 mm MVQ 70 ShA is an industrial sealing component designed to maintain elastic sealing performance across a wide operating temperature range.

Construction and Material Characteristics

The sealing ring is manufactured from MVQ silicone elastomer with hardness 70 ShA. This material offers excellent thermal stability, resistance to aging and very good flexibility even at low temperatures.

The O Ring has a circular cross section which ensures uniform compression when installed in a sealing groove. MVQ silicone material provides reliable sealing performance even under long operating cycles and repeated temperature fluctuations.

Unlike standard NBR or EPDM rubber compounds, silicone MVQ does not become brittle in cold conditions and retains flexibility in applications exposed to temperature changes.

This makes silicone O Rings particularly suitable for industrial equipment exposed to outdoor environments, air systems and equipment requiring chemically stable sealing materials.

Operational Advantages

Silicone MVQ O Rings offer outstanding elasticity across extremely wide temperature ranges. The material retains flexibility in low temperature environments while maintaining sealing properties at elevated temperatures.

Another advantage of silicone sealing rings is resistance to UV radiation and ozone exposure, which allows them to be used in outdoor equipment and installations exposed to sunlight.

Silicone elastomers also show excellent aging resistance and long service life in air and dry environments. Because of these properties, MVQ sealing rings are frequently used in industrial processing lines, ventilation equipment and sealing systems in laboratory technology.

The large dimension 279.3x5.7 mm is commonly used in industrial machinery covers, vessel sealing systems and large mechanical assemblies requiring stable static sealing.

FAQ

What temperature range can a MVQ silicone O Ring operate in
Silicone MVQ O Rings typically operate between about -60 C and +200 C depending on the specific industrial application.

Where are large silicone O Rings such as 279.3x5.7 mm commonly used
They are frequently used in industrial tanks, processing equipment covers, filtration systems and large mechanical assemblies.

Are silicone O Rings resistant to UV exposure
Yes. Silicone elastomers have excellent resistance to UV radiation and ozone which allows use in outdoor environments.

Can MVQ silicone O Rings replace NBR seals
In many temperature critical applications silicone O Rings are preferred because they remain flexible at low temperatures where NBR may harden.
