We have developed pressure-resistant underwater connectors that have reached the international first-class technical level and have independent and controllable technology. the rubber material is more flexible, and has better deformation performance and insulation performance under the same strength.This series of connector products has excellent environmental resistance, sealing performance, mechanical reliability, etc. Easy to repair and operate. It can be used in occasions immersed in deep water for a long time, and the working depth can reach 7000 meters.HQKJ rubber series products have undergone rigorous environmental tests and index experiments. The products can be widely used in marine scientific research, military exploration, offshore oil exploration, marine geophysics, nuclear power plants and other industries.It can be matched with SubConn series underwater connectors to realize installation interface and functional interchange.
