GR/C2
Description
GR/C2 is a double-acting scraper energized by an O-Ring that prevents the entry of mud or other contaminants, optimizing service life.
It can be used as a secondary seal in combination with the GCR (single-acting seal).
  • Good scraping results even with hard-to-remove dirt;
  • Good hold of the residual oil film on the piston rod;
  • Excellent sliding properties;
  • No stick-slip;
  • High resistance to hydraulic flows.
