Not mine or my wife's, but a SS 1/2 by 1 1/4 fully threaded pipe nipple. I have looked at Home depot, Lowe's, and Ace Hardware. I called a plumbing supply company with no luck as well. The nipple goes with my weldless ball valve for my keggle. I have managed to cross thread my 1/2 pipe cast nut to the nipple. I don't want to pay shipping from Northern Brewer, where I got it, and I don't need or can afford to buy a bunch of stuff to justify the shipping cost.
