Product Description

The O-Ring 5x1.5 NBR 70 Shore is a precision technical sealing component designed to create a reliable seal between mating mechanical surfaces. Installed in a properly designed O-ring groove, it deforms under compression to prevent leakage and improve sealing efficiency in mechanical assemblies.

The designation 5x1.5 indicates a 5 mm inside diameter and a 1.5 mm cross section. These two dimensions are the primary selection criteria. The inside diameter determines the shaft or component size, while the cross section defines the compression characteristics and the amount of groove filling required for proper sealing performance.

Manufactured from NBR (Nitrile Butadiene Rubber), this O-ring provides the material properties commonly required for technical sealing applications. The verified hardness of 70 Shore A represents the standard hardness used for a wide range of industrial sealing solutions. Selecting the correct material and hardness is as important as choosing the correct dimensions.

The operating principle of an O-ring is based on elastic deformation. Once compressed between two mating surfaces, the circular cross section fills the sealing gap and creates an effective barrier against leakage. Proper groove dimensions, clean installation surfaces and careful assembly are essential for optimum sealing performance.

The 1000-piece package is intended for maintenance departments, industrial plants, automation engineers, repair workshops and OEM production environments where frequently used sealing components must always be available. Bulk packaging simplifies inventory management while reducing purchasing frequency for commonly used O-rings.

When selecting an O-ring, both dimensions and material must match the original specification. Even small dimensional differences may affect sealing performance, installation quality and long-term reliability. For this reason, the 5 mm inside diameter, 1.5 mm cross section, NBR material and 70 Shore A hardness should always be verified before installation.
