Hello,
I am looking for a replacement part. The o-ring, u-ring, u-cup or gasket whatever it may be called that attaches to the membrane. I need a new one and am having trouble finding a replacement. A link or part number would be much appreciated!

Thanks in advance!

Found it!

In case anybody else has this issue it is called a brine seal and here is a link.

thanks for replying with this link. its a couple weeks before our season and i went to check on my dow XLE 4040 that was in a SMBS bath during the off season, and the brine seal became distorted and stretched out beyond repair... just from sitting in the SMBS. weird!
I looked everywhere. hopefully this fits my filmtec 4040...
