O-ring 5x1.8 Silicone VMQ 70Shore

Applications, Advantages, Technical Data

Main description

The O-ring 5x1.8 MVQ 70Shore is a precision-engineered silicone rubber sealing ring designed for reliable static and low-dynamic sealing in demanding industrial environments. Manufactured from high-quality MVQ (silicone rubber), this O-ring offers excellent thermal stability, flexibility, and long-term sealing performance, even under fluctuating temperatures.

With an inner diameter of 5 mm and a cross-section of 1.8 mm, this silicone O-ring is commonly used in applications where conventional elastomers are insufficient. MVQ material ensures stable mechanical properties across a wide temperature range, making this O-ring suitable for equipment exposed to heat, cold, or temperature cycling. The 70 Shore A hardness provides an optimal balance between elasticity and dimensional stability, ensuring consistent sealing pressure and reliable installation.

This O-ring silicone 5x1.8 is widely applied as a static seal, rubber gasket, or industrial sealing ring in sectors such as automation, electronics, medical devices, food-related machinery (non-grease applications), and light pneumatic systems. Silicone rubber is inherently resistant to ozone, UV radiation, and aging, which significantly extends service life in long-term industrial use.

Supplied in packages of 100 pcs, this product is optimized for B2B customers, maintenance departments, OEM production, and technical wholesalers who require consistent quality, repeatability, and fast availability. Each O-ring meets strict dimensional tolerances, ensuring compatibility with standardized grooves and housings.
