O-Ring 200x5 MVQ 70 ShA Silicone VMQ

Silicone O-Ring 200x5 for Industrial Applications

High Temperature and Environmental Resistance

Hydraulic, Pneumatic and Technical Sealing Use

Main Description:
The O-Ring 200x5 MVQ 70 ShA is a large-diameter silicone sealing ring designed for professional industrial applications. Manufactured from VMQ (MVQ) silicone elastomer, this rubber gasket ensures stable technical sealing performance in environments exposed to temperature extremes and atmospheric factors.

With an inner diameter of 200 mm and a cross-section of 5 mm, this O-Ring is suitable for large housings, tank covers, inspection lids, flanges and industrial enclosures. It is primarily used as a static seal where consistent compression and long-term dimensional stability are required.

Silicone MVQ material is known for its excellent resistance to both high and low temperatures, UV radiation, ozone and aging. The O-Ring 200x5 maintains flexibility at low temperatures and structural stability at elevated temperatures, typically operating from around -50°C up to +200°C depending on system conditions. This makes it a reliable industrial sealing component in HVAC systems, food processing equipment, energy installations and technical machinery.

The 70 ShA hardness provides an optimal balance between elasticity and mechanical strength. It ensures uniform groove compression and reduces the risk of leakage in static sealing assemblies. Compared to standard NBR rubber seals, silicone O-Rings offer improved performance in high-temperature and outdoor environments.

The O-Ring 200x5 MVQ 70 ShA is widely used in hydraulic and pneumatic applications where thermal resistance and durability are critical. Precision molding guarantees consistent cross-section geometry, supporting safe and efficient long-term operation.

For maintenance teams, engineers and procurement professionals, this silicone O-Ring offers a dependable industrial sealing solution for demanding operational conditions.
