Rubber flexible joints should be stored in a loose ground state as far as possible.
 
In order to avoid deformation of the tube body under pressure when storing rubber flexible joints, the stacking should not be too high; and the joints should be inverted often during storage, generally not less than once a quarter.
 
When storing rubber flexible joints, they should not be touched with acids, alkalis, oils and other corrosive liquids and gases and should be kept 1m away from the heat.
 
During the storage period, rubber flexible joints are prohibited from piling up heavy objects above the pile and avoid extrusion and damage from outside.
