Seals according to DIN 3869
Profile seals in accordance with DIN 3869 provide axial static sealing of the threaded joints.
Threaded joints are used in pipe fittings, in valves and fittings, in plugs and sockets, for example. 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....
