Well, I think I'm all done with building and acquiring the necessary pieces of equipment for all grain brewing. There's one thing that's been bugging me, however, dealing with teflon plumber's tape. I've put the tape on all fittings outside of the MLT and boil kettle, like where the ball valves screw onto the nipples, and where the hose barbs and ball valves connect. However, I did NOT put any tape on the interior connections, such as where my hose barb connects to the bulkhead on the inside of my cooler, or where I connect my Bazooka T-Screen to the bulkhead on my keggle. I was afraid that the higher temperatures of the wort in the MLT would be bad for tape. I'm especially concerned about exposing the tape to boiling conditions in the keggle.
So, am I all wet on this? Every piece of equipment I've bought, be it bulkhead fittings, the T-Screen, weldless thermometer, you name it, says to seal all connections with teflon tape, with no mention of the risk of higher temperatures. This tells me that it's not a concern, but the voice in the back of my head tells me otherwise. I also figured that I really don't have to worry about leaking in these spots since they're completely contained and submerged anyway, but on the other hand, I'm worried about the fittings somehow welding together without the tape (galling, I think the proper term is?). Are these concerns warranted?
