K83 is a double acting cover seal specially designed for staticapplications.

PRODUCT ADVANTAGES
• High operating pressures
• High reliability
• Interchangeable for o-ring and o-ring with back-up ring
• Easy and secure installation
• No need for additional back-up ring
• High wear resistant

APPLICATION
All the hydraulic applications that o-rings are being used.

SURFACE ROUGHNESS Ra Rmax
Sliding Surface  Ød ≤0.8 µm ≤3.2 μm
Groove Base   ØD ≤1.6 µm ≤6.3 µm
Groove Flanks  B ≤6.3 µm ≤16 µm

INSTALLATION
Easily assembled by hand. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.

NOTES
K83 is a double acting cover seal for inner sealing. The diffculties faced during an o-ring assembly such as twisting , ripping was solved with this design. It can be used without a back-up ring at high pressures. Due to the material , K83 does have good wear resistance to extrusion and shows good sealing performance in double acting applications.
