Applications of the 113x3.5 NBR O-Ring

The O-Ring 113x3.5 NBR 70 Shore is a widely used technical sealing component designed for reliable sealing in industrial applications. It is commonly applied in hydraulic and pneumatic systems, oil and grease circuits, pressure installations, industrial machinery, and maintenance operations. Due to its precise dimensions, this O-ring is primarily used for static sealing, and in suitable conditions also for low-speed dynamic sealing.

This product is suitable for both serial production and maintenance services, where consistent quality and immediate availability are essential.

Advantages of NBR Material and High Resistance

The O-ring is manufactured from NBR (nitrile butadiene rubber) with a hardness of 70 Shore A, which is the industry standard for technical sealing. NBR offers very good resistance to mineral oils, lubricating greases, fuels, and common hydraulic media.

Thanks to its stable mechanical properties, the O-ring maintains elasticity and sealing performance over long operating periods. The 70 Shore hardness provides an optimal balance between deformation resistance and ease of installation, resulting in high durability and reduced risk of leakage in industrial systems.
