Am I the only one who gets bad results with Kegland's instructions for screwing on Duotight connectors?
In their video, they just screw them onto MFL fittings by hand, and that's that. I also read I was supposed to screw them on hand-tight and then go 1/4 turn. In reality, I have to go maybe 1.5 turns past hand-tight to get the bubbles to stop. After that, everything is fine.
Moved the CO2 in my keezer to Duotight and EVAbarrier last night, and I lost quite a bit of CO2 to a loose Duotight. I checked the fittings for leaks when I installed them, but I believe the solution I used (Star San) was not bubbly enough to reveal everything. I omitted the nylon washers suggested by a nutty website (tried that before and ruined a couple of fittings) and used Teflon to cut friction. I think plain old keg lube or Super Lube would work just as well. I went hand-tight plus 1/4 and then used the Star San solution to check for bubbles. Things looked good, but then my CO2 tank pressure dropped.
Tonight I got out some solution made with Dawn and applied the wrench. All is fine now. I think.
Seems it would be useful to come up with a guaranteed method in order to help others avoid losing CO2 in the future. The way I did it tonight seems to have gotten the job done.
