O-Ring 80x3 NBR

Applications in Agricultural Hydraulics and Pneumatics

The O-Ring 80x2 NBR 70 ShA is a precision technical rubber seal designed for demanding operating conditions in agricultural machinery and industrial hydraulic systems. This size is commonly used in static and semi-dynamic sealing applications, where tightness, oil resistance, and long-term reliability are essential.

Typical applications include:

• hydraulic cylinders - sealing of glands and pistons in front loaders, tractor lift systems, and folding mechanisms,

• hydraulic valves and distributors - sealing of housing connections and sections,

• hydraulic pumps - sealing of housings and working interfaces.

Use in Tractors, Tanks, and Agricultural Equipment

The 80x2 mm sealing ring is widely applied in key assemblies of agricultural machines, where operational reliability and leak prevention are critical.

Common use cases include:

• agricultural tractors - sealing of oil filter housings, fuel system components, gearboxes, axle covers, and PTO connections,

• slurry tanks and vacuum tankers - sealing of connectors, couplings, and transfer interfaces,

• sprayers and irrigation systems - sealing of filter housings, large hose connections, and fluid distribution components.

Thanks to its material properties, the O-ring performs reliably in contact with hydraulic oil, water, and selected agricultural chemicals.
