The installation quality of O - ring has an important influence on its tightness and service life.Leakage problems are often caused by poor installation.
During installation, O - ring is not allowed to be scratched, malpositioned or twisted.Before assembly, sealing groove and sealing mating surface must be cleaned strictly;At the same time, apply grease to the surface to be passed through in o-ring assembly.
In order to prevent O ring from being cut or scratched by sharp edges such as sharp Angle and thread during installation, 15 ~ 30 leading Angle should be left at the shaft end and hole end of installation.When the o-ring needs to pass through the external thread, the special thin-wall metal guide sleeve should be used to cover the external thread;If the o-ring needs to pass through the orifice, the orifice should be inverted into the corresponding bevel shape to prevent the o-ring from being scratched.The bevel Angle of the groove is generally a=120 ~ 140.
