NBR O-ring 50x1.5 mm 70 Shore Technical Seal

NBR O-ring 50x1.5 mm 70 Shore Technical Seal

NBR O-ring 50x1.5 mm 70 Shore is a precision nitrile rubber sealing ring designed to provide reliable sealing in hydraulic systems, pneumatic installations and industrial machinery exposed to oils and lubricants.

Within the category of technical seals NBR O-rings, this dimensional configuration belongs to thin cross section sealing rings commonly used in compact sealing grooves where precise elastomer compression is required. NBR nitrile rubber is widely used in industrial sealing technology due to its excellent resistance to mineral oils, greases and many technical fluids used in mechanical systems.

The NBR O-ring 50x1.5 mm is frequently searched using dimensional queries such as O-ring 50x1.5, NBR O-ring 50 mm, rubber sealing ring 50x1.5 mm, or nitrile O-ring 1.5 mm cross section. These long tail dimensional searches typically appear when replacing seals in pumps, hydraulic valves, pneumatic fittings and industrial fluid control systems.

With a hardness of 70 Shore A, the nitrile elastomer compound provides an optimal balance between elasticity and mechanical strength. This allows the O-ring to compress correctly inside the sealing groove and maintain stable sealing performance under pressure, vibration and exposure to oils or lubricants.

In modern industrial machinery NBR O-rings are widely used because they combine durability, chemical resistance and reliable sealing performance across a wide range of technical applications.

Construction and Material

The sealing ring is manufactured from NBR nitrile rubber, an elastomer specifically developed for sealing environments exposed to oils, fuels and lubricants.

Key material properties include:

excellent resistance to mineral oils
good compatibility with hydraulic fluids
high elasticity and compression recovery
good mechanical durability in industrial environments

The circular cross section of the O-ring allows uniform compression inside the sealing groove. When installed between sealing surfaces the elastomer forms a tight sealing barrier preventing leakage of liquids or gases.

Because of these characteristics technical seals NBR O-rings are widely used in hydraulic equipment, industrial automation systems and mechanical maintenance applications.

Dimensional Compatibility

Correct dimensional selection is essential for reliable sealing performance.

The O-ring 50x1.5 mm corresponds to the following parameters:
