Aiming at the product hydraulic fitting sealing problems, the cause analysis and test research are carried on. The results show that fitting leakage fluid specifications are satisfied as improved component surface roughness with appropriate assembly and fastening torque. A range of torque parameter 130N.m-180N.m is suggested for process control to hydraulic fitting assembly torque. Taking necessary design and process improvement leads to well effects.
