Why Choose Us

Product application

Generally, the copper gasket adopts the local sealing with thread. Its sealing principle is that the two joint surfaces extrude the copper gasket, so that the two surfaces of the copper gasket fit closely with the two joint surfaces without any gap, so as to obtain the sealing effect. In order to achieve the sealing effect, annealing treatment is generally carried out before use, the purpose of which is to make the copper sealing ring soft, so as to achieve better sealing effect, and effectively prevent the corrosion of the gasket and the medium.
