I found these on ebay and was wondering if anyone has used them? and if they were worth it? I thought they looked interesting. But they say they are used in pressurized systems. But they should be fine in a sump right?

I have not seen these listed on MFK ever so Idk if they are new.

never heard of them before, definitely different.
and ya those should work in a sump no problem.

They dont look to have an overwhelming amount of surface area to them.
