O-Ring 59x3 MVQ 70 ShA Silicone - Industrial Seal

Silicone O-Ring 59x3 for Industrial Applications

High Temperature Resistance and Long-Term Stability

Hydraulic, Pneumatic and Technical Sealing Use

Main Description:
The O-Ring 59x3 MVQ 70 ShA is a precision-manufactured silicone sealing ring designed for professional industrial applications. Produced from MVQ (VMQ) silicone elastomer, this rubber gasket provides reliable technical sealing performance in environments exposed to temperature variations, UV radiation and long-term aging.

With an inner diameter of 59 mm and a cross-section of 3 mm, this O-Ring is primarily used as a static seal in housings, covers, flange joints and technical assemblies. The 70 ShA hardness ensures an optimal balance between elasticity and mechanical strength, allowing uniform compression inside the groove and reducing the risk of leakage.

Silicone MVQ material is known for its high durability and excellent resistance to both low and high temperatures, typically operating from approximately -50°C up to +200°C depending on working conditions. Compared to standard NBR rubber seals, silicone O-Rings maintain flexibility at low temperatures and dimensional stability at elevated temperatures. They also offer strong resistance to ozone, weathering and environmental exposure.

The O-Ring 59x3 MVQ 70 ShA is widely applied in hydraulic and pneumatic systems, HVAC installations, food processing equipment and various industrial sealing solutions. Its precision-molded cross-section ensures consistent sealing pressure and long service life in demanding operational environments.

For engineers, maintenance teams and procurement professionals, this silicone O-Ring provides a dependable industrial sealing component designed for reliable and stable performance.
