You must know that both metal joints and hose joints are very prone to leakage problems. In most cases, the ferrules are loosened or deformed due to the large external force or impact force on the pipeline. Therefore, we need to check the card frequently. Whether the sleeve is out of round and whether the cutting edge is worn, if the pipe end and the ferrule nut are not pressed tightly, the external force of the pipe...

The installation of hydraulic fittings is generally divided into the following 5 steps: 1. Pre-installed ①. An important part of the pre-installation of hydraulic joints and fittings directly affects the reliability of the seal. Usually a dedicated preprocessor is required. Fittings with small diameters can be pre-assembled in a vise. The specific method is to use a joint as the mother body, and press the nut and th...
