GR/C5
Description
GR/C5 is a double-acting scraper energised by an O-Ring that prevents the entry of mud or other contaminants, optimising service life.
Ideal for use in mobile hydraulic systems in harsh conditions. 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 residual oil film on the piston rod;
- Excellent sliding properties;
- No stick-slip;
- High resistance to hydraulic flows;
- Scraper for heavy-duty operation;
- Can compensate for bending of the rod and piston.
