Which coupling for which kettle?

[Landers]

I figured i would ask those who have more experience than I. I have the opportunity to set up my all grain kettles any way i want and had a question regarding full and half couplings. I was going to weld in the drain coupling the same for all three kettles and was thinking a full coupling for adding in a dip tube or other items on the inside. The return coupling at the top of the kettle i was also thinking a full coupling. I guess my question is when would you use a half coupling vs a full coupling and why? Maybe a thermometer port?

Thanks and have a great brew day,

Thermometer and sight glass are the typical use for half coupling.

Be sure you face them the right way and mark it so you weld it in right as they are tapered one direction.
