O-Ring 2x1.25 NBR

The O-Ring 2x1.25 NBR 70 ShA is a high-quality industrial sealing component made from nitrile-butadiene rubber (NBR). Designed for both industrial and automotive applications, this rubber seal provides excellent resistance to oils, fuels, greases and hydraulic fluids, while maintaining flexibility and dimensional stability.

The 2x1.25 mm dimensions ensure a precise fit in compact groove designs, making this O-Ring ideal for static and dynamic sealing in engines, pumps and valve assemblies. With a hardness of 70 Shore A, it achieves the perfect balance between elasticity and mechanical strength, delivering long-term sealing reliability even under high-temperature or pressure conditions.

Each package contains 100 pcs, making it an economical and convenient solution for production plants, maintenance departments and repair workshops that require continuous access to reliable sealing components.
