O-Ring 14x1.78 NBR 90 ShA

Construction and Material

O-Ring 14x1.78 NBR 90 ShA is a precision engineered nitrile rubber seal designed for industrial applications requiring compact dimensions and increased resistance to pressure extrusion. Within the nitrile NBR O-ring category, the 14x1.78 mm variant with 90 ShA hardness represents a reinforced sealing solution for small diameter shafts and narrow gland designs.

Manufactured from high quality NBR nitrile rubber, this O-ring provides excellent resistance to mineral oils, greases and fuels. The 90 ShA hardness ensures greater stiffness compared to standard 70 ShA compounds, reducing deformation under higher operating pressures.

The cross section of 1.78 mm allows installation in slim sealing grooves while maintaining consistent compression and sealing efficiency.
