The advantage of type Fig. 3 : It is very convenience for installation, when put the groove adown O-ring could be held in the groove and not drop; The O-ring could not enter the hydraulic system when the pressure is negative. The type Fig. 4 has only the later advantage of the type Fig. 3. The type Fig. 5 has no above advantage. ● 对公制
