O-ring NBR 70 Shore

O-ring NBR 70 Shore   O-rings are on the circumference closed ringshaped sealing elements, whose mode of action 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 a o-ring sealing is brilliant. Therefore, it is the most used sealing. Due to the economical production and the simple installation, the o-ring is unbeatable. The name of the o-ring consists of the dimensins of the inside diameter and the cord size in mm, as well as the material designation and its half (elasticity).
