I have a Polar 14 gallon SS boil kettle. Polar did a great job welding on the out fitting and a single half-coupling for the thermometer. But that half-coupling is a problem.
I was hoping to avoid putting another hole in the kettle when I install my whirlpool system. The best way to do that is to use the thermometer half-coupling to input my recirculation for my whirlpool. But they not only have a half-coupling, they welded on a washer (it appears) on the inside. So I can't install a 1/2" NPT x 1/2" compression fitting for my whirlpool tube.
Here are the pictures:
Is there any way to attach a tube on the inside of the pot using the 1/2" NPT half-coupling that's welded on the outside? I thought about a 1/2" x 3/8" bushing, but the ones I've seen don't take the female threads through to the inside. I've also seen something called a 'thru wall tank fitting', that does take the female (inner) threads to both sides. But the smallest one of those I've been able to google is 2".
I also tried jamming the 1/2" ss tube into a nipple (it's a close fit, so I considered soldering it in), but that is not only way ghetto, it is fairly permanent since I can't fully rotate the contraption to remove it once it is soldered in place.
So, any advice? I'm afraid it's going to be 'another hole', which isn't that bad. That SS soldering works really well after all...
