O-Ring 10x1 MVQ 70 ShA - Silicone Sealing Ring

Overview

The O-Ring 10x1 MVQ 70 ShA is a high-quality silicone sealing ring designed for reliable performance in demanding temperature and environmental conditions. Manufactured from MVQ (silicone rubber), this O-ring provides stable elasticity, excellent aging resistance, and consistent sealing properties in both static and low-dynamic industrial applications.

Key Features and Advantages

• Wide operating temperature range and long-term elasticity
• Excellent resistance to aging, ozone, UV and atmospheric exposure
• Suitable for systems requiring material purity and chemical neutrality
• Designed for hydraulic, pneumatic, laboratory and precision equipment seals

Industrial Applications

The O-Ring 10x1 MVQ 70 ShA is widely used in industrial equipment, laboratory devices, pneumatic control systems, food-related processing machinery (where silicone is acceptable), measurement instruments, and thermal control systems. It is an ideal sealing component where operating conditions involve variable temperatures or sensitive media compatibility requirements.

Main Description

This O-Ring 10x1 MVQ 70 ShA is manufactured from premium MVQ silicone rubber, offering high dimensional stability and resistance to thermal cycling. Silicone O-rings are recognized in industrial sealing applications for retaining flexibility at both high and low temperatures, making them suitable for environments where conventional NBR or EPDM O-rings may lose elasticity or degrade.

The 70 ShA hardness provides a balanced combination of sealing firmness and adaptability to mating surfaces, optimizing performance in static seals and gentle dynamic motion. The material’s inherent resistance to oxidation, UV exposure, and ozone prevents surface cracking and ensures long life even under continuous thermal stress.

Packed in sets of 100 pieces, this sealing ring supports efficient maintenance planning for machine service teams, OEM production lines, repair operations, and warehousing. It is commonly used in pneumatic valve systems, laboratory apparatus, sensor housings, electrical control units, heating equipment, and industrial process devices requiring stable and reliable sealing components.

This O-ring is chosen where cleanliness, temperature resilience, and material neutrality are essential to maintaining system reliability and preventing leakage or contamination.

FAQ

What is the operating temperature range for MVQ silicone O-rings?
Typically from approx. -50°C to +200°C, depending on application conditions.

Is silicone resistant to oils and fuels?
Silicone offers limited resistance to oils and fuels. For heavy contact with oils, FKM/Viton is generally recommended.

Is this O-ring suitable for static sealing?
Yes, it is optimized for static seals and light dynamic contact.

Why choose MVQ over NBR or EPDM?
MVQ maintains elasticity under extreme temperature variation and resists environmental aging better.
