COVERSEAL PSI SEMI STATIC/DYNAMIC

product

COVERSEAL PSI is a semi static/dynamic inside sealing element designed to replace O-ring or 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 PSI 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.

Note: COVERSEAL PSI is a double acting cover seal for inside sealing. The diffculties faced during an o-ring assembly such as twisting , ripping was solved with this design.

MATERIAL: PU 94 SH
