That is a gauge by a company called Man Law. It's ok... I'm not super impressed with their "tech support". I emailed them to ask what the thread pattern was. After explaining to the tech what a thread pattern actually was, he responded "it's 3/8"". I asked because I couldn't match the pattern at Lowes. I wanted to weld in a nut as a bung. The gauge came with a "nut" that is smooth and round, no walls like you'd expect so you could use a wrench to tighten it. He told me to "just finger tighten it and you'll be fine." So, needless to say I'm not super impressed with them, but the gauge seems to be fine, and it glows, so that's neat-o.Gizmo wrote:Quooole! So what kind of gauge are we looking at?
