Need Bung For Pipe-Threaded Sending Unit

Like the title says, I'm trying to install an automotive thermal fan control sending unit into the oil pan. I have a stand alone oil cooler with a fan. I bought a 3/8" male threaded sending unit (PIPE THREADS) and I'm trying to find a bung that will work with it so that I can weld the bung to my oil pan, and then the sending unit will thread into that.

My local hardware store gave me a bung from their galvanized pipe section. The sending unit does thread in, but it is not a tight enough fit in my opinion. It seems I would need to epoxy the sending unit in to this bung in order to not have a leak.

Any ideas? Maybe you guys have a different way of skinning this cat?

I'd tig weld something like this into the pan, then on the temp sender threads use liquid thread sealant.

Nevermind, I found that my local O'Reillys auto parts stocks ARP weld in bungs. That was easy.
