GFD ULTRA SEAL


Spring Energized PTFE-Seals

Surface Finish

(Rod and Housing)

The life expectancy of the seal and the sealing quality is also directly dependent upon the quality of the sealing surface.

We recommend the following surface finish.

Applications Sealing Medium
Gases and Cryogenics Fluids
Dynamic 0,2 ... 0,3 µm Ra (N3 ... N4) 0,2 ... 0,4 µm (N3 ... N5)
Static 0,3 ... 0,8 µm Ra (N4 ... N6) 0,4 ... 1,6 µm Ra (N5 ... N7)
Other non-sealing surfaces approximately 0,4 ... 6,3 Ám Ra
(depending on dimension)
