Fitting recommendations

In order to enhance the functional reliability and service lifetime of the sealing and guiding system, we recommend in the case of applications likely to involve elevated contamination of the medium in the system, e.g. in mobile hydraulics, that a combination of guide elements of fabric-based laminates (HGW) and PTFE compounds be used.
This has the advantage that any foreign particles entrained in the system circuit become embedded in the upstream PTFE material on the oil/fluid side, so protecting the actual guidance and sealing system against damage. This additional ring serves as an internal wiper, so countering the effects of contaminated media.

The mating contact surfaces should have an Ra value between 0,4 µm and 0,6 µm (microns).
