Main description (SEO)

The O-Ring 26,2x3 NBR 80 ShA is a precision industrial sealing ring designed for professional applications where reliable sealing, material stability and long service life are required. Manufactured from high-quality nitrile rubber (NBR) with a hardness of 80 ShA, this rubber gasket provides an optimal balance between elasticity and mechanical strength.

NBR is widely used in technical sealing due to its strong resistance to mineral oils, lubricants, fuels and many industrial fluids. The 80 ShA hardness ensures effective sealing without excessive deformation, making this O-Ring suitable for both static and selected semi-dynamic applications. Its dimensional stability supports consistent compression and minimizes the risk of premature wear.

The 26,2x3 O-Ring is primarily used as a static seal, but it also performs well in low-movement assemblies where controlled flexibility and sealing integrity are essential. Typical industrial applications include hydraulic and pneumatic sealing, valves, fittings, connectors, pumps, cylinders and machinery components exposed to oil-based media and pressure fluctuations.

Thanks to precise manufacturing and consistent tolerances, this O-Ring meets the expectations of maintenance teams, OEM production and industrial procurement departments. Supplied as a pack of 100 pieces, it is an efficient solution for B2B customers who require availability, repeatability and cost-effective logistics for ongoing operations.
