I have a Duda Diesel B3-36A-ST that has never been used. In fact the blue caps on the threads have never even been taken off. It has 1/2 npt on all sides. I'm selling it because it's just to long to fit on my beer stand. I bought it for 145. Asking $110 will ship but buyer paysView attachment ImageUploadedByHome Brew1445467062.022863.jpgView attachment ImageUploadedByHome Brew1445467076.825067.jpgView attachment ImageUploadedByHome Brew1445467087.460976.jpg
