I'm not a fan of weldless fitting only welded now that's out of the way
but this is what I did for a friends weldless fittings that has worked 100% drip free for years.
With the 40 qt. kettles he was having problems after every few brews with guessing when they would start dripping to even become bad leaks with his weldless fittings with the valve only relying on the half crushed resistance of the "O" rings for preventing turning and wobbling of the valves. A totally POS setup on my way of thinking.
Too tight and it would spit out the "O" rings. I machined a step into larger diameter nuts as well made 1/4" thick washers also with a step to confine the "O" rings. With half the orange high temp not black rubber "O" rings thickness between the nut or washer to kettles when just making a full "O" ring contact on the kettles before any compression has begun. The nut and thick washer make solid contact against the kettle sides with the solid metal washer and nut bottomed out against the kettle with app 40 ft/lbs torque applied. This solid metal to metal contact made for solid wobble free and leak free valves that do not turn.
The weldless idea is great if a person does not want to have fitting welded to their kettles, it's just that an improvement on weldless would make them a solid trouble free fitting if the manufactures stopped making a product cheap as possible just to make a sale. The brewer is the one that has the problems after. Done ranting. Carl.........
