The dust ring is a reciprocating seal installed on the hydraulic and pneumatic piston rod, mainly used to remove dust from the surface of the piston rod and prevent pollutants from entering the sealed cylinder body. Its material is mainly rubber, and in recent years, it has gradually adopted a combination structure of PTFE and O-ring to improve wear resistance and service life. They can be assembled in grooves according to standard ISO 7425/1.
