Kettle Dip Tube Question

Reading some of the threads today made me think about dip tubes. Has anyone tried using something like:

with something like:

screwed on the inside as your tube? Assuming you measured your height correctly, you ought to be able to get it perpendicular with the bottom of the kettle.

A couple other questions come up though.

1 - Would tightening the threads be enough to get an air tight seal, or would you need something else on the threads (such as tape)?

2 - Is the 90 degree angle too much for the siphon?

This would certainly work. Just remember that in order to use a dip tube you have to have tubing connected to the ball valve nipple in order to keep a siphon going.

The nipple screwed on the inside would not have to be tight in order for the siphon to work. I made a copper dip tube that screws into the ball valve in my keggle and I have to keep it unscrewed a bit to get it pointed down 90 degrees. I think that as long as it is screwed in by a few threads, there should be a good enough bond to keep the siphon once the water level fall below the valve coupling.

I also forgot to add that if you screw the 90 degree nipple into the inside coupling of a ball valve and you still have a large gap from the end of the nipple to the floor of your kettle, you can always get some silicone tubing. It is rated to 500 degrees.
