The dust ring is an essential reciprocating seal installed on both hydraulic and pneumatic piston rods, meticulously crafted to ensure the smooth operation of heavy machinery. Its primary function is to expertly remove dust and debris from the piston rod's surface, thereby safeguarding the sealed cylinder body from harmful pollutants. Traditionally produced from superior-quality rubber, recent advancements have led to the adoption of a sophisticated combination of PTFE and O-ring structures. This innovation significantly heightens wear resistance and extends the product's service life. Engineered to perfection, these dust rings can be elegantly assembled in grooves in accordance with the prestigious standard ISO 7425/1.
