Sealing Performance and Durability

Main Description

The O-ring 208x16 NBR 70 ShA is a large-size industrial sealing ring designed for reliable and long-term performance in demanding technical applications. Manufactured from NBR (nitrile butadiene rubber) with a hardness of 70 ShA, this O-ring provides an optimal balance between elasticity, mechanical strength, and resistance to deformation, making it a standard choice for professional industrial sealing.

With an inner diameter of 208 mm and a cross-section of 16 mm, this O-ring is intended for applications requiring large-diameter static sealing and controlled dynamic sealing. NBR material is well known for its excellent resistance to mineral oils, greases, fuels, and typical hydraulic fluids, which ensures stable performance in hydraulic and pneumatic applications. The compound also offers good abrasion resistance and low compression set, contributing to high durability over extended operating periods.

The O-ring 208x16 NBR 70 ShA is commonly used as a rubber gasket in heavy industrial machinery, pumps, valves, flanges, pressure vessels, and large sealing housings. Its robust cross-section supports effective sealing under pressure while maintaining dimensional stability during temperature fluctuations typical for industrial environments. This makes it suitable for maintenance, OEM production, and industrial overhaul projects where reliability and repeatability are essential.

As a versatile technical sealing component, this O-ring integrates easily into standardized grooves and sealing systems. It is widely selected by engineers and maintenance teams due to its predictable behavior, compatibility with standard industrial media, and cost-effective performance. In systems where downtime must be minimized, the proven properties of NBR ensure dependable sealing and long service life.

Designed for professional B2B use, the O-ring 208x16 NBR 70 ShA supports consistent sealing performance across a wide range of industrial sectors, including manufacturing, energy, fluid handling, and mechanical engineering.
