Precautions for hydraulic fluid fittings

When the joint of the rubber hose is buckled, if the size of the pipe is too large, the inner rubber layer and the winding steel wire of the rubber hose will be broken, causing oil leakage. If the size is not enough, once the pressure is too high, it will cause oil leakage, or even the high oil pressure will cause the rubber pipe joint to come out directly. If it hits the staff, it will cause casualties. Therefore, please be sure to master the reasonable seizure size, subject to the shrinkage of the inner hole at the tail of the joint, the compression of the national standard joint is 0.1-0.4mm, and the compression of the common joint is 0.1-1mm. Due to different manufacturers of rubber hose and joint sleeve, their sizes are also different.
