Design and use of O-rings

O-ring design and improper use will accelerate its damage and loss of sealing performance. Experiments show that if the design of each part of the sealing device is reasonable, simply increasing the pressure will not cause damage to the O-ring. Under the working conditions of high pressure and high temperature, the main reasons for the damage of the O-ring are the permanent deformation of the O-ring material and the gap bite caused by the O-ring being squeezed into the sealing gap, and the O-ring is twisted during movement.
