I am building a keggle to be used as a boil kettle and would like to know if it is ok to use a copper tube and a brass coupler for the dip tube or will this impart undesirable flavors or other nasties?

Copper should be fine it would be the brass that i worry about. Most brass from China has lead in it..

IMO, the minute amount of lead that is present in brass is nothing to be concerned about. You can passivate brass to mitigate the potential hazard, but I never bother and I'm still above ground.

IIRC, Palmer details the passivation process in How to Brew:

http://www.howtobrew.com/

"Cleaning Brass
Some brewers use brass fittings in conjunction with their wort chillers or other brewing equipment and are concerned about the lead that is present in brass alloys. A solution of two parts white vinegar to one part hydrogen peroxide (common 3% solution) will remove tarnish and surface lead from brass parts when they are soaked for 5 minutes or less at room temperature. The brass will turn a buttery yellow color as it is cleaned. If the solution starts to turn green and the brass darkens, then the parts have been soaking too long and the copper in the brass is beginning to dissolve, exposing more lead. The solution has become contaminated and the part should be re-cleaned in a fresh solution."

IMO, it's primarily for the bling appeal. I would use stainless myself if it were not for the high cost. Secondary considerations for me are the somewhat limited variety and availability of the fittings.

He who seeks the bling shall find the bling no matter how well concealed. Bling appreciation is in the eye of the bling beholder. A Mercedes in the barn is as good as a Mercedes in the driveway.

Just to note, since I started building my AG equipment I have noticed on the packages of my brass fittings that I purchase from Home Depot all say "Lead Free"

Well i know in California that some things sold there are different then other places, as far as the chemicals in the products. I was at Home Depot here in Texas and i was looking at some brass couplings and hose bards and i looked at the package "Contains Lead-Illegal for sale in California and some other state" I think it was Cali and Vermont or something, but California for sure. Thought that was kind of a weird thing to see on a product package.
