O-Ring 25.3x2.4 NBR 80

NBR 80 O-ring for general technical sealing

Balanced hardness and oil resistance

Hydraulic and pneumatic applications

O-Ring 25.3x2.4 NBR 80 is a high-quality rubber sealing ring designed for professional technical sealing in industrial applications. It is intended for B2B users who require reliable performance, dimensional accuracy and compatibility with common working media used in hydraulic and pneumatic systems.

The O-ring is manufactured from NBR rubber with a hardness of 80 ShA, providing an optimal balance between elasticity and mechanical strength. This material offers high resistance to mineral oils, greases, fuels and petroleum-based media, ensuring stable sealing performance during continuous operation.

With precise dimensions of 25.3x2.4 mm, the sealing ring fits accurately into standard grooves and provides effective static and semi-dynamic sealing. It is widely used in hydraulic and pneumatic sealing systems, including cylinders, valves, pumps, distributors and industrial machinery components. The selected hardness reduces the risk of deformation under pressure while maintaining good surface conformity.

The simple geometry allows for easy installation and minimizes the risk of damage during assembly, which is important for maintenance efficiency and system reliability. This O-ring is a proven solution for industrial applications where durability, tightness and predictable sealing behavior are required.
