O-Ring 90x3 MVQ 70 ShA Silicone

Silicone O-Ring 90x3 for Industrial Applications

High Temperature Resistance and Long-Term Stability

Hydraulic, Pneumatic and Technical Sealing Solutions

Main Description:
The O-Ring 90x3 MVQ 70 ShA is a precision-engineered silicone rubber seal designed for professional industrial use. Manufactured from MVQ (VMQ) silicone elastomer, this industrial sealing ring delivers stable technical sealing performance in environments exposed to temperature fluctuations, UV radiation and long-term aging.

With an inner diameter of 90 mm and a cross-section of 3 mm, this O-Ring is primarily used as a static seal in housings, covers, flange connections and industrial assemblies. The 70 ShA hardness provides an optimal balance between elasticity and mechanical strength, ensuring uniform compression within the groove and minimizing 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 system conditions. Unlike 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 90x3 MVQ 70 ShA is widely used in hydraulic and pneumatic applications, HVAC systems, food processing equipment and various industrial sealing installations. Its precision-molded profile ensures consistent sealing pressure and long service life in demanding operating environments.

For maintenance departments, engineers and procurement professionals, this silicone O-Ring represents a dependable technical sealing component designed for reliable industrial performance.
