The problem with getting a valve to properly seal is because of the curvature of the kettle. So, if you are installing a weldless valve fitting try this: After drilling the hole, assemble your ball valve, but Leave off the o-rings!! If you have two washers, put one on each side, next to the kettle. Then tighten as tight as you can. This will cause the kettle to flatten around the installation area. Disassemble and reassemble with the o-rings in their proper place.
