Card sets of connections, in China only developed in recent years, it's connecting and sealing principle is that when the nut tightened up, the card sets under pressure to edge into the tube outer wall of the Department of bite, card sets and outside the cone with the joint under pressure All cone density in vivo, which can reliably prevent the leakage.
