also the tee you see sticking out is threaded in the inside for the temp sensor
Copper, brass or bronze would be best, but a galvanized tee would work.
A 4-way or cross tee should be threaded at all 4 openings.
However, you may need an adapter for the temperature sensor if the threads on it do not match the tee threads.
