O-ring 80x2 NBR

Applications in Agricultural Machinery and Hydraulics

The O-Ring 80x2 NBR 70 ShA is a precision technical rubber seal designed for use in agricultural machinery and hydraulic systems. This size is commonly applied in static and semi-dynamic sealing points, where reliable tightness and resistance to operating media are required.

Typical applications include:

• hydraulic systems in agricultural machines,

• valves, distributors, pumps, and hydraulic blocks,

• oil and lubrication circuits,

• seeders, sprayers, cultivators, and auxiliary agricultural equipment.

Thanks to its geometry and material properties, the 80x2 mm sealing ring is widely used by maintenance teams and service workshops supporting agricultural operations.

NBR 70 ShA Material - High Resistance in Field Conditions

The seal is manufactured from NBR (nitrile butadiene rubber) with a hardness of 70 Shore A, which is the industry standard for hydraulic and pneumatic sealing applications. This compound provides high resistance to mineral oils, greases, fuels, and typical working fluids used in agricultural machinery.

NBR 70 ShA offers an optimal balance between elasticity and mechanical strength, ensuring dimensional stability, resistance to deformation, and long service life under varying pressure and temperature conditions commonly encountered in field operation.
