product

COVERSEAL OP(a) is a static in/outside sealing element designed to replace O-ring + back up ring combination.

PRODUCT ADVANTAGES:

  • High operating pressures
  • Interchangeable for o-ring and o-ring with back-up ring
  • Can work under severe conditions
  • No need for additional back-up ring
  • High wear resistant
  • No twisting on assembly

APPLICATION:

All hydraulic applications in which O-rings are used.

INSTALLATION:

COVERSEAL OP(a)  is assembled by hand. If using assembly tool the mounting area should not have any sharp edges. Before mounting the COVERSEAL must be lubricated with oil system.
