To all current owners of our #6 dampers (DL6 and DR6 dampers):

We are introducing new output shaft sealing U-rings for our #6 and #3 dampers.
These U-rings have "almost zero" friction and it improves our dampers.
All new #3 and #6 dampers are produced with new U-rings from today.

You can easy replace your current standard O-rings by new U-rings also.
Please use a needle to take out old O-rings from #6 dampers.
