Whether it is a hydraulic transition joint or other pipe joints, their biggest role is to connect between the pipe and the pipe, since there is a connection, there is an excuse, that can not completely guarantee that the connection of the pipe will not produce leaks, which requires people will prevent in advance to do so.


In fact, not only hydraulic transition joints, in the hydraulic system, both metal pipe joints and flexible pipe joints have leakage problems. For ferrule type pipe joints, most of them are subject to large external force or impact to make the ferrule loose or the tube end face deformed and cause leakage, at this time, you should check whether the ferrule is out of round, whether the edge is defective, whether the tube end is intact and the compression degree of the ferrule nut. For flared pipe joints, most of them have excessive flare, resulting in flare deformation or cracks that cause leakage, at which time the front end can be cut off and re-flared. 　　




There are also some hydraulic transition joints and other joints in some of the "о" shaped ring by the end or the outside diameter of the seal occasion leakage because, "о" shaped ring aging or deformation and cause leakage; "о "O" shaped ring assembly is not in place, so that when the two planes are connected, the pressure is not flat or "O" shaped ring is cut to cause leakage; "O" shaped ring is not compacted, the elastic deformation is not enough to cause leakage; "O "shaped ring stop groove is too deep and cause leakage. In this regard, it is necessary to re-select the "о" shaped ring with the same outer diameter and thicker cross-section. No matter what material, first of all, the seal should be checked for damage, deformation, aging and excessive roughness, etc., and then take appropriate measures.
