Thank you to both people who have responded. I really like both ideas. I was thinking of an o-ring , but was unsure of the size to use. It would definately work better then teflon tape.

Thank you for the information, It is very strange. I went into the menu and the Adaptive Pressure box was selected. My current negative pressure would sit around 420 and refill around 380. My current negative pressure sits around 399. The interesting part is that my required negative pressure dropped to 184. The only other setting I changed was I added in the data source to the pump speed from my Octo. I think I will monitor the system for a few days and see if it drops the current pressure to a...

Running a new standalone leakshield for about a week. The system has been up and running for about 2 months with no leaks. My issue is the sytem seems to develop bubbles but not in one area.

I am startiing to build up a small collection of ultitube parts. With my latest build I am using an ultitube multiport lid.
