The tightening of the threaded joint causes the elastomer profile (easily deformable) to press inwards, achieving the seal between the surfaces to be sealed. The profile gasket is designed to prevent leakage of the fluid to the outside, thus avoiding a loss of pressure. In addition, its peculiar geometry avoids twisting during assembly and in its housing once it has been installed....
