$3 Weldless Kettle Bulkhead
 
Ok, a few bucks, YMMV depending on what tools you have already.

$1 Nibco 604 Copper male adapter 1/2" NPT to 1/2" pipe (5/8" OD actual).
$2.38 for two pack. Hillman 3/4" stainless washers, item 21840 at Lowes

Short piece of 5/8" soft copper tubing but you can do it with a piece of rigid 1/2" pipe with a 90 degree elbow if you have to.

I already had the oring but a #314 is what you'd want to get.

The washer needs to be slightly filed open to get it all the way over the threads. After that, clean up the parts, apply an acid flux and silver solder the washer to the adapter.

The oring then goes on, through the kettle wall, then teflon tape, then the ball valve. If you can't get it tight, add the other washer between the kettle and valve.

very nice! (needed the 10 characters....)

Oh, this also works well for the Mcmaster male QD for returns and Herms coil access only the washer and oring goes outside the vessel.

The o-rings are silicone. You can buy them from bargainfittings.com or mcmaster.com

I like the simple and awesomeness of that bulkhead build.

what kind of flux do I need to solder the SS washer to the copper? I'm assuming I can't use regular flux, is this correct? Thanks

Bobby_M 04-14-2010 07:09 PM

It's got to be an acid flux that is good at wetting stainless. It comes in the stay brite silver soldering kits.

So simple. My home depot weldless bulkhead is ridiculous compared to this setup.

Yours uses like half the pieces.
