High strength pliersPrecision casting pliers high-density impurity-freepliers are not easy to break and Pressure relief valve switchTighten when pressurized Close when pressurized Refuse to spillThe fourth-generation double-layer thickening sealing system of innovative technology no longer has to worry about oil leakage Increase the uniform force on the pistonIncrease the diameter of the piston, the diameter of the piston is larger, and the force area after the die is increased, and the die is not easy to deform. Double sealLet the oil rainbow and the pressure rod "zero clearance.Closely attached to the table", Manufacturer: ZXZZAS
