I recently purchased two Tel Tru gauges and my smoker already has a 1/2" NPT set up for it so i just easily can thread the gauge and be done with it but trying to center it is a but challenging so should I try and get it just about right and then use that serrated kind of not to help tighten it? I'll leave a picture below to show..the left side door gauge threaded with ease but the right side not so much and i cleaned out the threads too.
