O-ring 19,2x3 NBR 70 ShA

O-ring 19,2x3 NBR 70 ShA Nitrile Rubber Seal 100 pcs

O-ring 19,2x3 NBR 70 ShA is a technical sealing ring made from nitrile rubber designed for reliable sealing in hydraulic systems, pneumatic installations and industrial machinery. With an inner diameter of 19,2 mm and a cross section of 3 mm, this O-ring provides stable sealing performance in mechanical assemblies that require resistance to oils, lubricants and industrial fluids. The product is supplied in packs of 100 pieces, making it a practical solution for maintenance departments, repair workshops and industrial production environments.

NBR nitrile O-rings are widely used in industrial sealing applications due to their durability, elasticity and compatibility with mineral oils and petroleum based fluids. The hardness level of 70 ShA ensures an optimal balance between flexibility and mechanical strength, allowing the sealing ring to maintain reliable contact pressure between sealing surfaces.

Construction and design

The O-ring 19,2x3 NBR 70 ShA has a circular cross section designed to create uniform compression between sealing surfaces. This simple design ensures effective sealing and prevents leakage of fluids or gases in mechanical systems.

NBR nitrile rubber combines elasticity with resistance to mechanical wear. The material maintains stable properties when exposed to oils, lubricants and many industrial fluids commonly used in hydraulic and pneumatic equipment.

A hardness rating of 70 Shore A is one of the most widely used standards in industrial sealing technology.
