O-Ring 132x3.5 NBR

The O-Ring 132x3.5 NBR 70 ShA is a high-quality industrial sealing ring made of nitrile-butadiene rubber (NBR), designed for demanding applications where reliability and resistance to oils, fuels and lubricants are essential. With an inner diameter (ID) of 132 mm and a cross-section (CS) of 3.5 mm, this O-Ring provides a secure and precise static seal for mechanical assemblies and fluid systems.

The NBR material (70 Shore A hardness) combines excellent oil and fuel resistance with mechanical strength and flexibility, ensuring stable performance under pressure, temperature fluctuation and mechanical stress. This makes the O-Ring 132x3.5 NBR 70 ShA a preferred solution for hydraulic systems, pneumatic valves, fuel circuits, compressors, and industrial machinery.

Due to its precise dimensions and standard profile, this sealing element fits many common grooves, making it a universal replacement for a wide range of industrial and automotive components. NBR O-Rings are the industry standard for hydraulic and pneumatic sealing, offering high resistance to mineral oils, greases, and petroleum-based media while maintaining elasticity and long-term dimensional stability.
