These things are incredible
I have bought many of these items in the last two years. They work perfectly for my adjustable racking cane in my sanke fermenter, my HERMS coil install, in my adjustable sparge arm, etc... They allow you to adjust stainless tubing on the fly to your own needs! Great design!!
If you are using these under pressure please use the stainless compression rings which come with it, as the vitron or buna-n o-rings will not hold pressure.
