Three Parts Coupling Patent

Traditional coupling only includes ferrule and fitting. The fitting is easy to take off under very high pressure, which seriously threatens workers’ lives. Compared with the traditional coupling, the Three Parts Coupling designed by Jingbo is much safer. The middle band and the fitting are interlocked and more tightly. The fitting could bear more pressure and never takes off. It is 100% safe without any leakage.
