O-ring NBR 70 Shore

O-ring NBR 70 Shore   O-rings are on the perimeter closed ring-shaped sealing elements, the mechanism of which is based on the deformation of the cross section. They are endlessly made of elastomer materials in forming tools through vulcanisation. The simplicity of the form and the reliability of the function of the o-ring sealing is genious. It is therefore the most used sealing. The economic production and the uncomplicated installation make the o-ring unbeatable. The name of the O-ring consists of the dimensions of the internal diameter and the cord size in mm as well as the raw material name and its hardness (elasticity).
