I've been using them for 3 years now. Started with just 10 to try them out, Then I ordered more bags of 10 each because they work so well. As older saddles develope a leak, these new ones go on and all new lines use these too, cheaper, easier to use and seal better, an unbeatable combination.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
