Over the past 2 years, I have not run into one person (other than a couple other SF members) that know this. I always find myself smacking my head with my palm.
Despite this, I've always had good luck with sealing pipe threads with teflon tape. For steel pipe threads, use a lot of it. I assume that your leaks are originating from the larger fittings. I use about 10 feet for a 2" thread.
