Prevention of leaks at hydraulic pipe joints - Zhuji …

In the hydraulic system, whether it is a metal pipe joint or a hose joint, there is a problem that leakage is easy to occur. For ferrule type pipe joints, most of the pipe is subject to large external or impact forces, which will cause the ferrule to be loose or the pipe end face deformed to cause leakage.
