George I was introduced to teflon tape as a thread sealer fifty years ago as you probably were too. Lately I have heard teflon tape is is a thread lubricant and it might seal the threads too. In a perfect world we should not need thread sealer but not many pipe threads are cut perfectly centered with consistent thread depth all the way around, meaning Chinese. I have put together a lot of hydraulic pipe fittings with no sealer and they sealed up just fine but maybe the oil was the lubricant allowing me to get it a bit tighter. Plastic fittings are supposed to not need a sealer but anyone who has pumped liquid nitrogen through plastic fittings finds out the fittings need teflon AND pipe dope together and the fitting might still leak.
