An RGP scraper ring (or RG with dust lip) is a component used in hydraulic and pneumatic systems to prevent the entry of impurities, such as dust and dirt, into rods with alternating linear motion. This type of scraper, thanks to its specific shape, ensures that the rod stays clean, protecting seals and mechanical parts from damage and extending the system’s service life.

In detail, the RGP scraper ring is characterized by:

• Metal body covered with rubber: This provides both strength and flexibility, allowing it to adapt to the rod and housing tolerances.
• Scraper lip: The main part that comes into contact with the rod, removing impurities.
• Dust lip: An additional element that provides extra protection against the ingress of external particles.

The main function of the RGP ring is therefore to protect sealing elements and guiding parts from wear caused by contaminants, ensuring reliable operation and extending the system’s service life.
