Also inside hole diameter of Guinness keg is smaller, so if you are planning to add thermowell or dip tub you will have less space to work with.
thanks so much Zazabnf !!!
But now I am more confused....http://www.brewershardware.com/2-Tri-Clover-Fittings/
They say a 2" tri clover will fit to a Sanke....do the Tri Clover sizes refer to the inside dimension not outside?
I guess my original question should be, what size, if any, tri clover fitting will seal up a Guinness keg?
