I have been following this thread for awhile but I have yet to come across any posting of what size people are using to pull Couplings and half coupling thru the keg walls.
What I am looking for are Concentric reducers to stretch the hole out for the couplings.
The sizes I need them for are 1/2" couplings and 1" half coupling for electric elements.
What is the rule of thumb. Next size down from what you are wanting to pull thru?
I found some on grainger, but not sure what size I should get. They are not cheap being stainless.
Bottled: Honey Wheat, American Wheat, Kolsch, Chocolate Porter, Oatmeal Stout
Kegged: Falconer's APA, Honey Brown Ale, Guinness Draught
