Silicone O-Ring MVQ 90x5 70 Shore A

Overview

The MVQ 90x5 70 Shore A Silicone O-Ring is a high-performance sealing element designed for static sealing and low-speed dynamic applications operating across a wide temperature range. Manufactured from MVQ (VMQ) silicone rubber, it maintains excellent elasticity at both low and high temperatures while providing outstanding resistance to ozone, UV radiation and weathering. These properties make it suitable for long-term operation in demanding industrial and outdoor environments.

Industrial Applications

The O-ring is widely used in food processing equipment, beverage machinery, medical devices, laboratory instruments, HVAC systems, pneumatic equipment, packaging machines, electrical enclosures, lighting systems, pharmaceutical equipment and OEM machinery requiring reliable sealing under varying environmental conditions.

Construction

The seal features a precision-moulded 5 mm circular cross-section with an inside diameter of 90 mm, providing uniform compression and reliable sealing performance. The flexible silicone compound simplifies installation, minimizes compression set and maintains sealing efficiency during repeated thermal cycling.

Material

The O-ring is manufactured from MVQ (VMQ) silicone rubber with a hardness of 70 Shore A. Silicone offers excellent resistance to temperatures from approximately -60°C to +200°C, as well as outstanding resistance to ozone, ultraviolet radiation and ageing. MVQ is not recommended for prolonged exposure to mineral oils, fuels or concentrated petroleum-based fluids.
