O-Ring 15.3x2.4 NBR 90 ShA

O-Ring 15.3x2.4 NBR 90 - 100 pcs Oil-Resistant Hard Seal

The O-Ring 15.3x2.4 NBR 90 ShA is a high-hardness sealing ring designed for demanding industrial and automotive applications. Packaged in 100 pcs, it is the perfect choice for workshops, OEMs, and maintenance departments requiring reliability, oil resistance, and long service life.

Key Features

• Material: NBR (Nitrile, Buna-N), hardness 90 ShA - excellent resistance to oils, fuels, and greases.

• Dimensions: Inner Diameter (ID) 15.3 mm, Cross Section (CS) 2.4 mm.

• Temperature range: approx. -30 °C to +120-140 °C, depending on medium and conditions.

• Hardness 90 ShA: higher resistance to wear, extrusion and deformation under load.

• Improved compression set resistance - maintains sealing performance under pressure and high stress.

Applications

• Hydraulic and pneumatic sealing

• Engines, pumps, gearboxes, transmissions

• Agricultural and construction machinery

• High-pressure and high-temperature applications requiring durability

Why choose 90 ShA hardness?
Compared to standard 70 ShA O-rings, 90 ShA provides increased stiffness, wear resistance, and reduced deformation, making it ideal for high-load, high-pressure environments.
