Dyna-Plex 21C Cursa Hydraulic Oils

Dyna-Plex 21C Cursa Hydraulic Oils

Heavy-Duty Off-Road, Industrial

Dyna-Plex 21C Cursa Hydraulic Oils are high quality, extra inhibited oils designed with hydrocracked Group II base oil, for use in multi-functional applications where long oil life is required. These oils provide steady, reliable performance as a hydraulic medium. They are filtered to remove external contamination and contain special O-ring conditioners to prolong hydraulic component life.

  • Seal swell agents prevent leaks and demulsifiers enhance separation and removal of water
  • Supply 5,000 hours of service without extreme oxidation problems
  • Provide excellent resistance to foaming, rust and wear
