Metal hose consists of three parts, metal preparation network, metal bellows, various types of installation fittings, fittings for the flange type, there are also threaded, quick-connect type and chuck type.

1、Saving time and labour: when breaking and connecting the oil line through the quick coupling, the action is simple and saves time and labour.
2、Saving oil: when breaking the oil circuit, the single valve on the quick coupling can close the oil circuit, the oil will not flow out, avoiding the loss of oil pressure.
3、Environmental protection: When the quick coupling is broken and connected, the oil will not be spilled to protect the environment.
4、Unique equipment design, easy to transport: large equipment or hydraulic tools that need to be carried easily, use quick couplings to disassemble and transport, and then assemble and use them after arriving at the destination.
