High pressure hose and fittings assembly withhold the amount and mode selection improperly withheld

High pressure hose and fittings assembly and withhold the amount of the withholding way inappropriate choice. Or joint structure, material, size selection is unreasonable, can lead to pressure hose and fittings too tight or too loose, causing early damage joints. Assembly, if the withholding amount is too small, that withhold joints between the weight of too loose with the hose when under the effect of Hydraulic tube fittings  hose during the initial period there may emerge from the joint; withheld if excessive, then withhold joints and hose too tight, easily lead to the hose inner layer of localized damage, deformation, cracks, high pressure oil from the weak rupture directly into the layer of wires, and then he went along the gap between the wire coat tail ejected, or along the wires of the layer has been somewhere he went to build up, so that the outer plastic drum kits produced even rupture. Hose and connectors in the assembly, if the withholding too fast, easy to cause damage to the inner rubber layer and wire breakage, so that premature failure of the hose in use. In addition, the joint design is unreasonable, jerry, processing of poor quality, can also cause damage to the inner glue; if improperly fitting material selection, not reach high pressure hose assembly requirements. Will shorten the life of high pressure hose
