If the withholding amount is too small, that the joint between the hose and the weight of too loose with the high-pressure hose connector assembly, hose during the initial period it is possible to emerge from under the action of the hydraulic joints; if the withholding amount is excessive, and the joint overextended hose, the hose inner easily lead by local damage, cracks.

     High pressure oil from the ruptured directly into the wire layer, and then he went along the gap between the wire coat tails discharge, or has fled to accumulate somewhere along the wire layer, the outer layer of plastic drum kits produce even rupture. Hose and fittings in the assembly, if the withholding too fast, likely to cause damage to the inner plastic layer and wire breakage, so that the hose in use prematurely.

  In addition, the joint design is unreasonable, poor processing quality, can also cause damage to the inner plastic; if connector material inappropriate choice in the withholding process easy to deformation, thus affecting the quality of withholding, so that shorten the life of the hose.
