O-ring 19,5x2,5 NBR 70 ShA

O-ring 19,5x2,5 NBR 70 ShA Nitrile Rubber Seal 100 pcs

O-ring 19,5x2,5 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 19,5 mm and a cross section of 2,5 mm, this O-ring provides effective sealing in mechanical assemblies where resistance to oils, lubricants and industrial fluids is required. 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 among the most commonly used sealing components in industrial engineering. Their compatibility with mineral oils, lubricants and many petroleum based fluids makes them suitable for a wide range of hydraulic and mechanical systems. The hardness of 70 ShA provides an optimal balance between elasticity and mechanical durability.

Construction and design

The O-ring 19,5x2,5 NBR 70 ShA has a circular cross section designed to provide uniform compression between sealing surfaces. This simple geometry allows the seal to maintain reliable contact pressure and prevent leakage of fluids or gases.

NBR nitrile rubber offers good elasticity and strong resistance to mechanical wear. These properties allow the sealing ring to maintain stable sealing performance in systems exposed to oil based fluids and mechanical loads.

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