I thought I'd buy a yellow teflon tape from the USA. Well it isn't. It is made in the EU which means the European Union as shown in the attached photo. I am very disappointed, first of all I paid double for this yellow teflon tape thinking it was made in the USA and not the yellow teflon tape that was made in China at Home Depot. The yellow teflon tape does not work. I've tried 3, 4, and 5 turns on a 1/2 NPT natural gas line connector. He still loses some natural gas on all 3 attempts. That yellow teflon tape made in the European Union sucks.
